Considering some of the posts I've read I'm starting to get scared of the above drug. I asked my GP several months ago if I really have to take it. His response was that it 'locks in the Ical-D3' which I take six days a week, along with my steroids. The AA says about standing or sitting upright to prevent being sick. What I want to know is why is it so important not to be sick? Can the AA burn your mouth to tummy tube?
