The limits on sweetener have been introduced recently I believe. "In my day", there wasn't a limit - sweetener can give gas, painful even (smelly too - particularly with those sugar free sweets and gums).
If I'm for limiting one's use of sweetener to the bare minimum in Cruise is to hopefully reduce somewhat any sweet tooths before moving into Conso where temptations are harder to resist.
Slimdreamer - are you close to your "true weight" now? Your BMI looks good, and your target low, but I can't recall whether you have kids, your age etc etc. Try posting menus in the menu section for a while. You might find that things have crept in...
