I've been on xanax on and off (mostly on) for over 20 yrs. It started as needed, then time would pass and I would be ok, then took some as needed again. Never felt like I abused it. (.25-.5mg only). For the past 1-2 yrs. I have taken it everyday b/c of insomnia and nervousness. This summer, after being on xanax xr between .5-1.0 mg. 2x day - I started getting all kinds of physical symptoms, including anxiety, but it felt different than it ever did before. The insomnia got worse, I am racing all the time and the memory stinks. I think I met my tolerance level and refuse to take more. I want to taper off and put a call into my dr. I've been getting panic attacks this year after not having them for a long time. I don't know if I should try klonopin or neurotin while tapering off the xanax, b/c reading about the withdrawal is very scary. Any comments or help here is appreciated.
