I do take seroquel....it's for taming down the nightmares and is classified as an anti-psychotic...another reason that it was prescribed was to take care of hearing voices and seeing things that others did not....I have been taking it for several years and it does have a sedative effect but as I've said that's not why I take it....Talk with your doc [a psychiatrist?] about your concerns about taking meds...Hopefully you have a good working relationship ......You can also do a web search on the medicine....Also ask your doctor what the side effects are [you need to ask that about any medication] I am on several meds which make it possible for me to lead a functional life and to be able to gain the benefits of therapy....Also ask your doctor if there is something else you can take instead if you are very concerned about taking seroquel....Is this the first medication you've been put on???? I can understand your concern about taking medication....I was also but since I couldn't stay functioning I took the chance and went with it....I do have an excellent doc and therapist to rely on...They are very familiar with PTSD...I hope that this answers some questions for you....If you decide not to take it after gathering your information discuss it with your doctor....If you are already taking a medication...DO NOT ABUPTLY STOP IT as you will get physically and psychologically ill...I wish you well and keep coming back to this forum as we are all very supportive of each other and there's a lot of information here GIVE PEACE A CHANCE
