I posted this reply when I first started to withdraw from Effexor and looking forward to the day when I could eliminate ambien from my daily cocktail of drugs. After 6 months of gradual withdrawal from Effexor, I'm back on it. Severe withdrawal and decreased levels of serotonin are to blame. Therefore, I am still dependent on ambien for sleep. I don't know if I can even attempt an ambien withdrawal until and if I can get myself back to some sense of sanity from the effects of withdrawing from Effexor. I am very upset and depressed right now so I don't plan to change anything else right now.
