i was in rehab and aftercare for 6 months because of my adhd medication... horribly, horribly addictive in my case
i sure did lose the weight though, but not in any healthy way
I'm sorry you had to go through that. I seem to be unable to get addicted to anything for some reason. I'll have my obsessions with stuff that may last from a week to a year, but they go away. For instance, in my bartending interest phase, I was mixing drinks every night because 1. it gave me practice 2. I liked how the drinks tasted 3. It was fun to get tipsy--I tried to avoid going beyond that though. 4. I was gaining weight and a lot of that went to my chest, which I liked.
However, after a couple of months, I grew tired of that and pretty much just stopped drinking altogether, just because I didn't feel like drinking. That's about the closest I've ever come to getting addicted. Also, I was hooked on coffee for a while, but I didn't like being dependent on it, so I weened myself off it, while catching up on sleep, and only have a cup like once every month or so. It's weird, but I think either ADD or OCD actually prevented me from being addicted. Since I need the meds to function (which have a similar effect to coffee), I plan to continue taking them for the time being and if I feel a.) that I'm addicted or b.) that I don't want to be dependent on them, I'll just talk to my doctor about stopping. It's really about as simple as that for me. Of course I do make sure to do it slowly to minimize any physical addiction symptoms. I just had a dosage increase a couple of days ago, and I think my doctor said I'm now at a "normal" dose. I just want to take as little as possible while still being able to function productively.
As for losing weight, I started doing that fast myself. I've got one of those scales that measures body fat percentage and I've adjusted my diet so that my fat percentage is now dropping, although my weight stays on the low end of the range that it fluctuates in.
