I am 22 and have always had a low tolerance to medications. Prior to taking Propecia, I would always take the smaller or half dose of X medication and get the same results as if i had taken a full dose. I am also prone to get the side effects associated with the drug. A 1/2 dose of Nyquil makes me feel like a zombie the next day. I was prescribed adderal and would only need 1/4 of the dose to get the effects yet I still couldnt sleep 10 hours after i had taken the the pill. Etc, Etc.
Not surprisingly, propecia gave me great hair growth after only a week of usage but i also got all the side effects.
Not only medication, but I noticed that my muscles would grow after just one visit to the gym and if I took a few days off I could notice them getting smaller.
Has anyone else felt that they had a low tolerance to medications or noticed similar changes in body type as a result of physical activity or lack of? Does anyone know why my body is so vulnerable to medications/physical activity and if this may be a reason why I am experiencing side effects from Propecia?
