You shouldn't have much of a dependency after 45 days. But still, I'd suggest tapering down the doses you are taking... that's always the safest way to quit benzos. I was prescribed clonazepam (Klonopin) daily for 6-7 years. Now I've switched to diazepam (Valium) and I'm tapering down that. I'm now down to 16mg's a day, and the withdrawals can be a nightmare at times, but it still beats quitting cold turkey which will probably kill me.
This. Metabolisms vary - apparently, some people can CT from benzos after years of daily use and experience no withdrawal, while others have thrown grand mal seizures after only a few weeks of daily dosing followed by complete cessation. The Klonopin's your friend here, as it has a longer half-life than Xanax, but if you could get hold of some diazepam, that would be better yet. (I transferred from high dose Xanax to high dose Valium, then started tapering down, I've been using daily for years, and thus have some very bad nights and the hour before my next dose is
not fun, but it's not unbearable either). Booze is more ambiguous - some say moderate drinking can help, but alcohol lowers your seizure threshold when it wears off, and drinking on my taper has lead to a few slips - get a little tipsy, figure 'fuck it, I'll just have one more extra pill tonight', and then find I've taken 15 of the fucking things. A beer or two probably won't make much difference, but heavy drinking's almost certainly going to make it rougher and more dangerous/protracted.
Take it slow and careful, and good luck: I wish I'd had the sense to start a taper as quickly as you did, you really shouldn'tt find it too traumatic after a month and a half. But don't take the risk of trying to CT - there's no way of knowing how quickly a particular metabolism's habituated to benzos, and better to play safe than be flopping on the floor in agony and shock, or find yourself experiencing even moderate surges of anxiety, sweats and shakes in public.
