I also took Seroquel 100mg for awhile for severe anxiety. You're right it will make you sleep especially at first. The grogginess would also follow into the next day. However, my anxiety was to a point where that sedation was a good thing. I also was not prescribed it for bipolar disorder or psychotic disorder. I don't suffer with those either. It was only for the anxiety. There were times that it might have calmed the anxiety somewhat, but by no means eliminated it. However, I was thankful to have the medication for sleep. You probably just need to get adjusted to the med. Also, meds. list every possible side effect known to man if you are reading the full pamphlet. I had no problems with it and was probably on it for about a year or so. I also take Effexor XR 150 mg. for depression. The main med. that has helped my anxiety problem is an anti-seizure drug called Lamictal. That's not to say that I don't still have some problems at times, but nothing near what I suffered before. My disorder has been a part of my life on and off for nearly 30 years. Most of that time it was controlled with Prozac, but then it became so severe and affected me so often that I had to have real help. I found a psychiatrist that really cared and he finally tried the anti-seizure med. and it has changed my life. Most people probably wouldn't need that type med., but the disorder I have is believed to have been partly the result of a bad head injury in a head-on collision about 1 1/2
all this began. Anyway, I would keep giving the Seroquel a chance because the more it gets in your system the more you will adjust to it and not be so groggy and feel weird. At least that was my experience. Hope this has helped somewhat. Best to you.
