Hiya the prob with most medicines is they are hi in sugar n carbs so won't allow u to go into ketosis! So if u r I'll n it helps I'd say keep taking it and u will still lose. Seeing as it's ur first week u may not have as much of a big loss as without going into ketosis it will literally be fat loss only. So just prioritise and your health comes first! Remember u don't have to be in ketosis to lose on cd it just makes the whole process a little easier. Hope you're feeling well again soon xx
