Big numbers symptoms and conditions

I'm on 240 mg a day and its no fun at all. I've built up a big tolerance to it, so much that even at this high of a dosage, I could fall asleep in no time at all. I've been at this dose fir like 4 years now. The good thing is that I have lost a lot of weight and managed to keep it off - going from a juniors size 11 to a 3 is the best thing thats happened though. Probably the only good thing. Otherwise, its made me different in many ways. I get to feeling that I just want to be left alone a lot so I can do my own thing, whatever that may be cause it varies. Some days I have a lot of energy, get lots done (cleaning, errands, some exercise classes, stuff like that), and other days I just feel like doing nothing. Mood swings are not uncommon for me, but I have always been that way I guess. Oh well, I guess if it works for you, take it. Its worked for me, but its about time I start to think about getting off of it as its effectiveness has run its course, at least I think it has. And I don't want to try anything else, its simply time to quit the ADD drug scene entirely. But like I said, if it works for you, then go for it. Just watch out cause it can build up on you fast like it did me, and you don't want to be taking as much as I do. (Its prescribed that way for me, BTW. I don't use it illegally).
