Flight response symptoms and conditions

I have been on Seroquel for about a month and a half.
When I first began to experience anxiety, I was given antidepressants starting with Celexa,(didn't work) Zoloft( made me feel worse), and Trazodone(same effects) , along with anti-anxiety medications.Nothing was working, and I ended up with Serotonin syndrome- HORRIBLE experience- did not sleep for a month, and it was as though my "fight or flight" response was on "hyperdrive".

Finally went to a Pdoc instead of a general practitioner,and he took me off what I was on . He put me on 50 mg. of Seroquel in the a.m., and 50 mg. in the p.m. before bedtime. I improved within several days, and have felt like myself for the most part ever since. I am thankful especially to be sleeping! Have gained some weight back, but since the serotonin syndrome caused me to lose 20 pounds in a month and a half, that is good. The first couple of weeks or so I had dry mouth, but that has gone away. There have been no sexual side effects like the ones caused by zoloft- that makes both my husband and myself happy.
Just hope if I continue to exercise and eat right that I won't experience the weight gain everyone is talking about.
My life is extremely stressful right now due to long-term circumstances beyond my control, and this medication is helping me to cope! Besides feeling some mild depression and grief due to those circumstances, I am just thankful to be functioning well again!

ive been taking for 2 years im lightheaded all the time dry mouth and im more nervous and anxious when i take it. at first it was helping me.Now it just makes things worse and trying to stop it is hard.I'm trying to dose off of it now i was taking half of 1 mg a day then 1 mg a day now im trying to half the half and im just getting worse i wouldn't recommend taking alprazolam(zanax)yes it calms you down for a little bit bit in the long run its no good.Oh yeah have bad dreams on it(a side effect) and also wake up with racing feeling at night maybe 5 times a night.

I started having panic attacks while taking Percocet. I am a chronic alcohol user, and I am saying this just in case it rings a bell for anyone. I have since stopped taking Percocet (about 3 days). I was a habitual/recreational user ... meaning that I took them when available, but I did not always have them. Since my last dose, I have been having recurrent panic attacks that are very scary. They include physical symptoms (heart pounding, cold and hot flashes, feeling of difficulty breathing, sweating, shaking) - and the much more scary mental symptoms (fear of death, walls closing in, inability to think or concentrate, vivid dreaming, fear of people, etc.). It appears that some other people have had issues like this, but not everyone. Can someone share their story with me. Has anyone had similar experiences ? Do they go away at some point ? Is it withdraw (I am not sure since they started while I was using them - but continued after I stopped) ? I have heard that it just takes some time, but it is very scary. I get some relief by drinking ... in fact almost complete freedom from most of the symptoms, but I can't just drink all day. Please help.
