I took Serzone at age 14-18 and the Effexor XR for three years in my 20s. On Effexor, I could only sleep one night a week. The other nights, I would just sit up, wide awake. About night 5-6, I would sit up crying because I was so desperate to sleep. And the one night I got sleep, I think it was pure exhaustion because I never dreamed at all. I fully believe the Effexor is the reason I still struggle with sleep now. I get a good week here and there, where I sleep all night, but after three weeks of sleeping only 3-4 hours a night, a full night's sleep makes me feel incredibly tired the next day.
I probably have a sleep debt of about a million hours..........
I also refuse to take any of the prescription sleep meds. I am super sensitive to them and spend the next day with a hangover.
