My general practitioner prescribed Prozac for my anxiety. I did not tell her that I was interested in taking it for my eating disorder because I didn't inform her of my bulimia. She prescribed 10mg for the first week and then 20mg thereafter. I'm reading the reviews and it sounds like the most common dosage is 40mg for bulimia treatment. I'm only 120lbs, I'm just wondering if that has anything to do with the low dose I received from my doctor, or if it's just the fact that I didn't reveal what I was truly seeking the drug for. I haven't started taking it yet, so I can't speculate on the change/ or lack thereof in my symptoms. Can anyone share a similar experience?
