Shit man. You just substituted one addiction for a worse one in a lot of peoples eyes. Benzo dependency is no joke. You need to come off incredibly slow. Try reducing your dose by 15-25% a day and see how you feel.
Let's not be too dramatic...a little over a month on benzos is perfectly reasonable (1-3 month courses, when medically justified, is acceptable) and the fact that you've only been taking 3mg a day which is within the clinical dosage range means that while you will experience some withdrawal symptoms they won't be too extreme- brutal insomnia, heightened anxiety and maybe 'brainzaps' (strange muscle spasms) for a week-week and a half. Not that it won't suck the monkey, it absolutely will when layered over PAWS, but I seriously doubt that you've developed a dangerous (seizure inducing) dependency.
I'd probably go for a rapid taper, go down to 2mg and hold it there for 3 days, drop down to 1mg for another three days and depending on how you're feeling either drop off there or go down to 0.5mg for 3 days. In my experience the most disruptive element of 'minor' benzo withdrawal is the insomnia- the cumulative exhaustion & complete inability to sleep really takes its toll...and the temptation to take a little junk to get a nights sleep is very strong.
To put things into context, when I kicked a ~300-500mg morphine/day habit I did it in a blaze of benzos. The first 10 days I took 20-40mg of diazepam for the general daytime unpleasantness and 12-27mg midazolam (vials, plugged- so about equivelent 24-50mg midazolam orally), then I dropped down to 20mg of diazepam/day and 20-40mg temazepam/night for roughly another 2 weeks. I was on extremely heavy doses of multiple powerful benzos for 3 weeks and I barely experienced any withdrawal, just rebound insomnia. I didn't take any for about 2 weeks, then the PAWS hit like a motherfucker and I spent another month taking ~10-25mg of alprazolam each night to sleep (yes, equiv 200-500mg diazepam a night)...I did a short taper from ~20mg down to ~4mg as I was running out. THAT was brutal, fucking terrible insomnia...to the point that after sleeping about 4 hours over 4 day I took some junk and slept for 20 hours (yes, dumb) and that was enough for me to get through the last of it. The withdrawal lasted about 10-14 days and although the insomnia was kinda crippling (you just can't do shit when you're that overtired), but compared to coming off a heavy junk habit -even with all the benzos- it wasn't that much of a big deal. Had I not fallen into a benzo bender I'm pretty sure I could have avoided all my withdrawal symptoms.
I'm not trying to trivialise the situation, I'm just telling you that in my experience (which may have no relevance to you) the withdrawal after approx. 2 months of ultra-high doses (the equivelent of hundreds and hundreds of mg of diazepam) was not particularly severe as far as benzos go. That seems to be their main redeeming feature- unlike opiates, even when taking massive doses you really do need to spend quite a bit of time taking them to develop any serious dependence.
Now if you were to stay on them for another 60 days then yeah, sure, you could run into problems. But even then, as long as you don't follow my lead and go completely overboard on your dosage it's unlikely to be anywhere near as bad as your opiate withdrawal.
Yes benzo withdrawal can be more unpleasant and dangerous than opiates, but I'd put money on the withdrawal from 3mg alprazolam/day will pale in comparison to a 180mg/day oxy habit. And I doubt you have to worry about seizures at this point, as I said, 1 month is well within medical guidelines.
Good luck with handling the PAWS and coming off the benzos, the worst of it (from my experience) is over...all you've gotta do now is take those few last steps over the finish line.
Oh and one other thing- do not drink alcohol when you're coming off the benzos. It DOES ward off the withdrawal somewhat, but it also massive increases the risk of seizures. I know it's tempting and I drank a lot after I came off the benzos completely (post benzo-withdrawal), but heavy drinking is really a step in the wrong direction.
