Xanax or any other Rx never helped me, it only made me feel worse the next day and I couldn't tell what was side effect and what was withdrawal. Everyone is different so don't let the internet freak you out; find what works for you and do your best. Your will power and strength will be what gets you through this and obviously you have a bunch of e-friends on your side rooting for you.
I couldn't really remember why I was taking any of this stuff in the first place, which is troubling. Everytime I tried to quit I couldn't make it past day 5-7 when the RLS, sleeplessness, sneezing and song verse repeats in my head really kicked up the volume.. so I'd always end up "making the drive". Two weeks ago I set an appointment with the local outpatient treatment center and its a humbling experience. Maybe talking to someone who sees the extreme side of it everyday would help or maybe help with a plan to get you back to par. Going there 6 days a week at 5am has helped me with getting a normal sleep schedule, starting my day and getting out of the house and active, and talking to other people who are going through much more intense things going on. I'm taking a small dose(6mg) of Suboxone and I've been two weeks without my drug of choice without any withdrawal. It's painful, I feel some shame and it's not exactly where I want to be; but it's a step in the right direction, and it just takes one to build momentum.
