My heart goes to anyone going through G withdrawals, I wouldn't wish that upon no one, not even mr. president Bush himself.
You'll have to tough it out. It'll last sometime, but hopefully in a couple weeks or a month you'll be back to baseline. Which can be a bitch, since you will just have gone through a traumatic experience AND still have all the underlying issues that made you resort to G as an escape.
From then on, it's up to you.
MY battle ended after years, thanks to a year and a half long psychoanalysis therapy, to work through what the fuck was wrong with me that I kept doing things that I knew would end up badly. I haven't touched G in 2 years now. Had people doing it in front of me, and nada. The idea disgusts me now, plus, people on G is just fucking annoying. I can do other drugs if I like, once in a fucking blue moon, but I don't think I could ever use G again. I don't know how it would affect me if I tried a dose now. I don't think I would get addicted again, but I'm not taking that chance. Whoever went through the withdrawal process, knows what I'm talking about.
Forget about G, move on, face the underlying issues. I'm sure you'll be alright.
