Hi Shane,
My husband has attempted to quit several times (longest was 2 weeks)...He complained of sleep problems and was up with night sweats, night terrors, the whole bit. Psychiatrist prescribed gabapentin at first (helps with anxiety) and now camprol to help with the sleep. Everyone is different, but he's sleeping MUCH better. Still struggling with the fully quitting part, but at least there's sleep.
Be careful with Ambien as it's a controlled narcotic and can be addictive if used for more than two weeks. Good luck and stay strong!
