How did you quit benzos? Do you know when the withdrawl symptoms stops? 1 week?
I was on Xanax for a few months. It got to the point where I needed a dose every 3 hours or I would have a full-blown panic attack. What I did was to begin by taking my first dose at a later time each day. I hit a wall around 3pm for some reason, but eventually I got through that. Then I switched to valium and only took it once a day. Over about a week, I reduced from 10mg valium to 2.5mg. After that, I just stopped taking it. I was off of it for nearly a month before I relapsed. Now I've been off it for 25 days.
I still have anxiety symptoms, but they're nowhere near as bad. The first two weeks were the hardest for me. I saw a definite improvement around my third week. Exercise, a good diet, comedies, and relaxing music will be your best friends. I've found that a bit of red wine is quite nice, but being hungover is a definite no-no, as it increases your heart rate and blood pressure and makes anxiety 10x worse.
The timeline for benzo withdrawal is different for everybody. It depends on a lot of things: how long you were on the medication, how bad your initial anxiety was and still is, the sources of stress in your life, your brain chemistry, etc. I've read stories of people who stopped feeling withdrawals after a week, as well as people who are still struggling after a year. Most of the latter stories, however, were from people who were on benzos for a seriously long time, like years.
In your case, I'd recommend cutting the dosage by about 25% and seeing how that makes you feel. If you have serious dependence, the general recommended taper time is a 10% reduction every two weeks. Of course, you can go much faster than this, and some people go much slower.
Edit: the reason you switch to valium for the taper is because it's longer-acting than other benzos. This allows for a more regular level of the medication in your system as you reduce your dosage.
