I tried Buspar while in the hospital and Reba. I didn’t find it helpful. It’s not an Atavan weaning med.
For me Buspar was worse than Adavan. Thinking
it was the answer to my twice a day doses of .5 in the morning and another at 2 pm. Still made me a zombie. Adavan was too strong for me anyway and at one point after 14 days (the recommended dose time). I was cut off suddenly with no weaning off (in other words, cold turkey). Was a nightmare. I was in rehab and had to beg for another one in the morning and at 2pm.

When I finally came home I called my psychiatrist and he switched me to Clonazapan (Klonopin) and it was half the dose of Adavan and it worked. After a couple to three days I stopped taking it completely after and Klonopin took over but it wasn’t as bad as Adavan. Klonopin was a bit less addictive and fairly easy to take. Not as strong as Adavan but just enough to take the edge off.

Some people can’t take Klonopin but it was better than the zombie causing Adavan.
No way was I able to quit Adavan cold turkey. I am however no longer sleeping all day after I got rid of the Adavan. There is a path to free yourself from Adavan it just takes a few days. Good Luck
