I took Seroquel for about 2 to 3 months about 9 years ago. I still have lingering side affects like I am still on it. I get the clumsiness, vertigo, heart attack symptom etc. when ever I get sick including just a mild cold. I also have other lingering side effects and am just curious if anyone else has had this problem. I have been checked for just about everything with my 3rd check for plugged arteries coming back normal. My calf's still have pain when walking and my calf muscles get tight and sometimes lock up. Please help.
