I take ritalin for seasonal depression. It really helps me. I take it about every other day in the hope that I won't become dependent on it. I know the danger that it could trigger a manic episode but nothing so far. I have been taking it for 3 years from September-April to help with SAD. The rest of the year I don't use it. So you are correct in saying that stimulants are being prescribed for off-label use and you are not the only one who "needs" them.
