I began taking ritalin 10 years ago at the age of 20... I started on 60 mg a day ( 20mg x 3 times a day) & by the age of 26, I believe, I was up to 80 mg daily (20 mg x 4 times a day). I'm now 30 yrs old & need more than just 80 mg a day because my tolerance has built up so much over the years... I would sometimes take 5, 6, or even up to 7 pills in one day just to make it through! ritalin is a wonderful & very effective drug, but like any other drug, it only takes more & more to have the same effect over time. I tried switching to vyvanse last month & it really didn't seem to help so I didn't care for it so much. I'm in the process of trying to find another med to help me & actually last throughout the day without having to take more than my prescribed dosage. my current doc seems to think I'm an idiot & won't listen to me when I tell him this, however, so I have an appt with a new kind of psychiatrist- a forensic psychiatrist- next week. hopefully he will listen like a doc should & help me find something or someway to fix this problem?

back to your question (sorry, I have a tendancy to wander off from the subject at hand... lol, tangents seem to have a magnetic pull on me), yes, ritalin is a wonderful drug, but just beware of its long-term tolerence build-up tendencies & risk of dependency. hope this helps!
