All I've tried is stratra and Bupropion

Yeah... Ritalin can be like that. There's different types of Ritalin in different doses, if Ritalin was working for you mostly I'd ask about that first. However, I know nothing about Dexedrine. Good luck on the medication journey, hopefully it won't be as much of a rollercoaster as mine was.

I have been taking Ritalin for years and it didn't stop working for me. When I felt that I needed more help I asked to increase the dosage. It's a great drug that can be taken safely every day and if it worked for you in the past it shouldn't change.

I have too switch between ritalin 20mg 3 times a day too adderall 30mgs 2 times a day off and on as my tolerance builds to the one or the other.
