Welcome to the forum. I hope you realise that we are not medically trained and therefore not in a position to give advice on medication, rather we try to support people with controlling their BG. I'm surprised you have been prescribed dapagliflozin as NICE only gave permission to use it on 30 May and still haven't released their final guidance to the medical profession.
Perhaps you'd like to tell us a bit more about yourself? Oh... and I do suggest you change your username because it's your full email and you'll get no end of spam having it in public.
