I had been on clonazepam for 13 yrs and have been trying to taper off over the past couple of years but ran into difficulty b/c of withdrawal side effects. More than one physician has strongly encouraged me to stop clonazepam because of it CNS side effects - and I have problems with cognition - the typical ones seen in CFS, and they are pretty severe problems with organizing my thoughts, concentration, consolidation of memory - I learn things for a couple days, and then the knowledge is gone. Anyway, I was given a presciption for Zolipem, 5 mg. I have been taking it for about 3 months most nights and completely stopped the clonazepam without problem. Now, of course I am concerned about developing a dependence on zolipem which will be just as hard to deal with. Any one out there with experiences using Zolpidem, problems with dependency, withdrawal?
