SWIM isn't allowed here ladies and squirts. it's no biggie, we aren't going to judge you.
here's why: Someone who isn't me (Use of this term is discouraged on BL; it is used on some forums in an attempt to avoid incriminating oneself, e.g. "SWIM is considering manufacturing meth, what does SWIM need to know?". There is no evidence that this provides any protection from legal repercussions, and it makes your posts hard to follow. Also, many people switch between "SWIM" and "I" in the same post. Finally, you shouldn't be incriminating yourself (drug synthesis, dealing, etc) on Bluelight anyway)
i rub the tips of my nails against my cuticles, it's borderline O.C.D. but i know it's not. only happens when i do stims or uppers. i use to have to hold my teeth together in a certain way. i've seen people blink their eyes a lot or in certain patterns, shaking their foot or leg more than just like doing it casually and a few other ways. some pick their toes or toe nails then there is the obvious face picking. it's habits and tendencies we all have when using, anxious or nervous.
not to get serious on you just be aware i've seen what happens when you do that too much, had someone bleeding for a few days and got infected. heard the urban legends of someone losing a finger but i call b.s..
some take it as a sign to quit or take a break when they are doing this all the time, especially when they're not aware of it and catch themselves doing it. other than that just don't freak out about it, nothing wrong. it's the way the brain works.
specifically i think it has to do with one part of the brain being over active and another part in reserve mode. also how the stim affects the nerves. i would have to defer to another member on that.
