My doc wants me to try Ambien CR at double strength. That means I only have 3 days' worth, coz the state plan refuses to cover it and so on my own I got a 7-day trial pack free from the company's website. Was wondering before I take it if it's worked for people here and if there were any side effects. I tend to have terrible side effects to this sort of med (one gave me horrible back spasms, a really rare SE for that med)so I'd like some feedback before I swallow any. Thanks.
