I've been prescribed and taking Adderall for almost 4 years now. I used to "up" my dosage (bad, I know) and then take 1-2 weeks off the meds to give my body a break (doctor suggested taking "drug vacation" on weekends or 2-3 days off it).
Anyhow, I haven't upped my dosage in a while and have been taking as prescribed for about 6 months now (and plan to keep it that way!). I HAD been increasing my daily mgs b/c it was less effective, and yeah, I know, it was b/c I developed a high tolerance to the medication. Honestly, even when I was taking more than prescribed, I wanted to get back to the lower mg I should have been taking. I was also in a more stressful point in my life -- went back home to help my mom through a divorce and my sister & I helped support her til she got back on her feet. I was having to work 2 jobs -- mornings/afternoons at a jewelry store in sales and at night I worked a paper route (2am to 5-6am). So I got little sleep. After 2 years of struggling like that, things got better & am in a well-paid career doing historical research where I make my own hours and no longer have to help support my mother.
Anyhow, as of 5-6 months ago, I noticed I couldn't take as much of the extra mgs as I used to and this number has slowly decreased to the point where I am now at my regular prescription dosage. It's like my tolerance level it going backwards. Which is good that I'm back to what I should be taking, it's just the manner in which I arrived that's worrying me. Am afraid I've damaged my nerves or brain or something similar and the decrease in tolerance is a sign of it. If so, should begin to get of the medicine altogether?
I have not spoken with my doctor about this issue b/c I don't want him to stop prescribing it to me since I really *do* need it to function & work properly. When I'm off it, I'm EXTREMELY hyper and when I try to work, I'll read, re-read, and re-read again a sentence and struggle to concentrate on what I'm reading. I seriously can only read fiction material when I'm not on medication. Non-fiction may as well be Japanese.
Sorry for the long post. I appreciate any help or advice. :)
