hello dear friends! i'm new around here. i really needed to ask about this because my doc is very optimistic(!) i constantly ask about my doctor and other doctors about if i have to take vitamin supplement for the rest of my life. they say no it's not necessary because you had gastric sleeve not gastric bypass. does is really tho? i'm reading all of you and everyone is taking supplements. can you inform me? i feel very stressed, i can't think about something else.
