My PDR just upped me from 150 to 225 because I was feeling tired and still had some symptoms. I am in my second week of the 150mg. SHould i have giving it more time?? I am kind of worried because it is the highest recommended dose. Is there much difference in the two dosages?? Is there anyone else that was on the 225 and felt better?? Any suggestions/advice is helpfull. Thanks DC :)
