Wow! 200 mgs of Zoloft and three mgs of Xanax. Have you ever blacked out before? You have to see your doctor. You may need a whole new regiment. I take Klonopin and find it to be a kinder gentler benzo. You can't just stop or switch your meds. It has to be done with your doctor's help. Slow and easy.....If you are not seeing a psyc doctor, you should consider it. They are more familiar with the types of meds you are taking.
It's making you what???did you mean black out?
Ummmm, what I think is that your overmedicated. 1mg is my max dose for the day and that's a lot! taking that 3 times a day is too much.. Anyone will tell you that. Don't try to just stop taking it either - your body is physically dependent on Xanax at this point. I know because my body is dependent on the 1mg/day. Benzos are weird drugs. Your doctor should be trying to control your anxiety with the SSRI's like zoloft, paxil, celexa and reduce the xanax to a healthier dosage.
This means you need to contact your prescribing doctor ASAP to determine what is going on. Don't abruptly stop your medications but definitely talk with your doctor.
