UGH!

I have taken my first and last trazadone. Since I started taking zanaflex, I am dealing with a dry mouth. The trazadone made it much worse. I also ended up very congested and felt like I was drunk. I ended up drinking sips of water all night and having to go to the bathroom. I could not use my cpap because I was so congested. This morning, I have a headache and feel like I have a hangover. I did sleep off and on and had what seemed like several dreams after 4:00 am. I going back to ambien. It helps a little and at least I do not feel like **** when I take it.
I don't know why I have such weird reactions to so many meds. I tried taking several different antidepressants three years ago and I just could not tolerate them.
