Adderall IR increase in tolerance?
I have been prescribed 10 mg IR. For 3 days it worked great. But I started feeling that the effect are decreasing. In day 4. I started taking 1.5pill 15mg (which my doctor told me-if needed increase to 15mg) and that worked perfectly for another 6 days when I again felt that the effect are fading away. On day 10 I started to take 20mg and so far it works fine. But I'm worried that I will require soon more. Is it normal to increase dosage within first month so rapidly? Is there recommended period to go from 10mg to 30mg?

I try to use it as recommended. Adderall has been very helpful so far and improved my life dramatically.

More info (maybe important maybe not); I'm 22 very athletic 185pounds working out daily for 2hours or more. btw: sorry for misspelling English is not my first language.
