I've been on Ritalin for about three years now. I've noticed that if I forget to take it, I get really, really anxious, almost paranoid and I also feel exhausted. And for the past maybe three months, I've noticed that later on in the day, I start feeling like I haven't taken it at all. I have never, ever, ever taken Ritalin to stay up all night or crushed it and snorted it or anything. Is this withdrawal? Can I be dependent on Ritalin even if I always took it as directed? I've wanted to go off of it, but any time I try, I get all this going on, and I live with two very, very anti-psychiatry people who will just lecture me even more if I say "I feel like ****, I didn't take my Ritalin." At this point... I'm pretty much only taking it to feel normal and appear normal.
