I'm a 19 year old male and was diagnosed with ADD about 6 months ago, which is rare because most of the diagnosis occur when a person is younger. My doctor put me on Adderall XR 10mg, I was slightly anxious/excited about taking it because I knew it could give you a "boost" so to speak. So, the next day I took it I turned into a completely different person, more sociable, relaxed and comfortable with my surroundings. I was able to focus on things at work that just left my mind in a foggy haze before. I thought adderall was my miracle drug and that I could continue on with my 1 pill a day for the rest of my life and be happy as can be. How wrong I was. Within 3 weeks I could hardly feel the effects of a single adderall and needed to up my dose, so my doctor doubled it. I was on 20mg XR and this only lasted me another month until I could feel the effects waning again. Eventually I was taking 4-5 10mg pills a day just to stay awake and alert and I decided I should stop taking them. There wasn't much of a physical withdrawal other than being terribly lethargic but the psychological withdrawal was horrible. I still think of starting them up again because they were such a boon to my life but at the same time I know it's just a short term thing and I'll be popping several again. In conclusion, Adderall is an excellent drug and does the job it's intended to do, however, tolerance develops RAPIDLY as does addiction. If you have an addictive personality steer clear of this drug.
