Help! Confused and afraid of abuse

[BOOYAHBOY]

For almost two years now SWIM has had a prescription for methylphenidate. First SWIM was perscribed 30mg if Ritalin a day but soon after starting this medication began using up to 70mg daily and was obviously abusing. SWIM would take all of his pills and then would suffer for two weeks of depression before he was able to refill. Luckily was able to admit this abuse and told doctor. Doctor then prescribed Concerta and SWIM immediately began abusing it in the same manor because it made him feel good. Now SWIM is using the transdermal patch daytrana. SWIM has done much better with the patch and likes being able concentrate better and be more productive. Doctor told SWIM that he is not abusing as long as he is using it for the intended purposes. Sometimes though SWIM likes to leave a patch on and stay up all night getting things done. This makes SWIM afraid that this is abusing also because he doesn't sleep. Doesn't have depression and withdrawals like he did when he used to abuse but still feels very guilty for some reason.

Does this sound like abuse/addiction?
