I've been on dexamphetamines for about 6 years now and have slowly found myself needing to increase the dose (started at 3 per day, increased to 4, then to 5, obviously with the dose spread out throughout the day). I've kept it at 5 for quite a few years now, I think since around 2001/2002...and I have only recently noticed that its not seeming to have any effect at all anymore - my brain feels clouded like there is cotton wool in my mind and I just can't seem to think clearly or focus on work (this was the problem before I started taking them)
...yet if I increase the dose (I have tried this a few times) the problem goes away and I can think clearly and continue with my work. If I keep to the normal dose I am not a very fun person to be around and find it very hard to do any work, even though I need it to earn a living.
I'm very wary of increasing the dose as I know what can happen and I don't want this to get dangerous...what do you think would be the best thing to do?
My psychiatrist said maybe to try Ritalin as it does not have any of the tolerance problems associated with dexamphetamines, but I thought I would ask a second opinion as I'm worried that Ritalin might have a lesser effect.
