Hi. I quit taking Seroquel 50mg. for sleep after 3 years on Feb 26, 2021. I stopped because of the horrible side effects it was starting to cause mainly heart palputations. I didn’t tirate I went cold turkey and boy did I ever pay the price. Severe sleep deprivation began the next night on Feb 27 and for 72 hrs. straight I did not sleep. Then I slept one hour. The next 3 weeks went like this. 48 hrs awake, 2 hrs of sleep, 72 hrs awake, 2-3 hrs of off and on sleep and on and on. I ended up in the ER and begged them to put me to sleep. They gave me Ativan and I slept a few hours in the ER. I feel like I damaged my brain and my heart after 3 weeks of severe sleep deprivation. On the 4th week, I believe the withdraw symptoms have begun to subside and my body is making me sleep during the day as soon as I close my eyes, I get hypnotic jerks and start snoring. I have been getting a 3-4 hours of sleep now every night for one week now, deep sleep and rem but the delima I am having is now I have what is called Chrimera State where my left brain is awake and I am on hyper villagence, while my right brain sleeps. I can hear myself snore and think and I can hear all the traffic outside, but yet I feel like I am sleeping. I feel myself going through the stages, and sometimes when I feel like I am going unconcious, I fight it my heart starts thumping and my anxiety skyrockets and I wake myself up. It is crazy. I have to catch up and was wondering if anyone knew how long it may take.
