Night-shift workers limiting sugar
If a fizzy drink is part of your break, check the sugars figure rather than assuming that a diet, slimline or light name tells you what is in the bottle.
Who is choosing a mixer?
Tonic drinkers comparing sugar and sweeteners
If you want tonic flavour, the choice includes products labelled with 0g sugars and light tonics that still contain sugar. Check the ingredients as well as the nutrition panel if particular sweeteners matter to you.
Workers planning food for a break
A mixer is a drink to have alongside food, not the food itself. Barking, Havering and Redbridge University Hospitals NHS Trust advises shift workers to eat regularly, with meals or lighter meals and snacks across a 24-hour period.
What should you check?
Start with the sugars figure, then decide whether tonic flavour, ingredients and pack size fit the way you take breaks.
| Priority | What to check | Your needs |
|---|---|---|
| Sugar content | Compare sugars per 100ml on the exact pack. Fentimans lists 0g for Soda Water and 3.4g for Naturally Light Tonic; Tesco lists 0g for Schweppes Slimline Tonic 1L. | I want a drink labelled 0g sugars, so a name such as “light” is not enough for me to choose it. |
| Type of mixer | Decide whether you want tonic or soda water before comparing their labels. Check the flavour description on the pack rather than treating the two drinks as interchangeable. | Tonic flavour matters to me, or I would rather use soda water as a plain mixer base. |
| Ingredients | Read the sweeteners and other ingredients on the current pack. Tesco’s listing for Schweppes Slimline Tonic 1L also carries a source-of-phenylalanine notice. | I need to check a named ingredient or notice before taking the drink to work. |
| Food for the break | Plan food separately from the drink. Barking, Havering and Redbridge University Hospitals NHS Trust advises regular eating during shift work, including lighter meals with snacks as one option. | A mixer will go with my break-time food, not take its place. |
| Storage after opening | Check the bottle’s instructions and choose a size you expect to use. Sainsbury’s says to refrigerate its Diet Indian Tonic Water 1L after opening and use it within three days. | If one bottle will last across shifts, I want its storage instructions to fit that plan. |
Common buying mistakes
-
Assuming “light” means no sugar
Fentimans lists 3.4g sugar per 100ml for Naturally Light Tonic, whereas Tesco lists 0g sugars for Schweppes Slimline Tonic 1L. The names do not replace the nutrition figures.
If 0g sugars is your requirement, check that figure on the pack you are buying.
-
Planning the drink but not the food
A mixer does not take the place of a meal or snack. Barking, Havering and Redbridge University Hospitals NHS Trust advises shift workers to eat regularly.
Bring food for your break and choose the mixer as a separate drink.
-
Skipping the ingredient notices
Diet and light names do not tell you which ingredients a particular tonic contains. Tesco’s Schweppes Slimline Tonic 1L listing includes a source-of-phenylalanine notice.
Read the exact pack’s ingredient list and notices if you need to avoid a particular ingredient.
-
Opening a large bottle without a use plan
Sainsbury’s instructs buyers to refrigerate its Diet Indian Tonic Water 1L after opening and use it within three days.
Check post-opening instructions when choosing between a bottle and individual servings.
An unfinished bottle may go to waste if you cannot use it within its stated period.
Brand and retailer references
These examples show why the label on a particular product matters more than a brand-wide assumption.
Fentimans
Its Soda Water and Naturally Light Tonic illustrate two different mixer choices.
- Fentimans lists 0 kcal and 0g sugar per 100ml for Soda Water.
- Its Naturally Light Tonic lists 18 kcal and 3.4g sugar per 100ml, so it does not meet a 0g-sugars requirement.
Schweppes
Slimline Tonic is a tonic option for readers checking sugars on the label.
- Tesco lists the 1L Slimline Tonic at 0g sugars and 2 kcal per 100ml.
- Tesco’s listing carries a source-of-phenylalanine notice; check the exact pack if that notice matters to you.
Fever-Tree
Refreshingly Light Indian Tonic is positioned by Fever-Tree as an alternative to its regular Indian Tonic.
- Fever-Tree states that Refreshingly Light Indian Tonic has 50% fewer calories than its regular Indian Tonic.
- That relative calorie claim does not establish 0g sugars; check the nutrition panel of the variant you choose.
Sainsbury's
Its own-label Diet Indian Tonic Water provides a 1L bottle option.
- Sainsbury's lists 2 kcal and less than 0.5g sugars per 100ml.
- Its product instructions say to refrigerate after opening and use within three days.
Tesco
Tesco lists own-label tonic alongside Schweppes Slimline and Fever-Tree Light options.
- Its range gives shoppers different tonic labels and pack formats to compare.
- Check the individual product page and pack for the figures and ingredients relevant to your choice.
Joybuy mixer options

Fever-Tree Refreshingly Light Mediterranean Tonic Water, 8 × 150ml

The 200ml bottles provide individual servings. If “skinny” is part of your reason for choosing it, compare the sugars and energy figures on the current pack with your other options.
Questions about night-shift mixers
Can a diet mixer replace food during a night shift?
No: plan food separately and have the mixer as a drink alongside it. Barking, Havering and Redbridge University Hospitals NHS Trust advises shift workers to eat regularly, whether through meals or lighter meals with snacks between them.
Does “light tonic” mean 0g sugars?
Not necessarily. Fentimans lists 3.4g sugar per 100ml for Naturally Light Tonic, while Tesco lists 0g sugars per 100ml for Schweppes Slimline Tonic 1L. Compare the exact products’ nutrition panels rather than relying on their names.
What if I need to avoid a particular sweetener or ingredient?
Read the ingredient list and notices on the exact pack before buying. Tesco’s listing for Schweppes Slimline Tonic 1L includes a source-of-phenylalanine notice; do not assume that every diet tonic has the same ingredients.
Can I keep an opened 1L diet tonic for later shifts?
Follow the instructions for that bottle. Sainsbury’s says to refrigerate its Diet Indian Tonic Water 1L after opening and use it within three days; another product may have different directions.
