If it helps at all, Trazadone helps most people get a decent nights sleep while also being an antidepressant. I found it a rather mild drug with out many side effects except a dry mouth. I took it many yrs. and it is not addicting. I don't recognize the name of the other one.
Like I said before .My psychiatrist does therapy as well and he is wonderful but I know they are few and far between. We are just a good match. That is going to be important no matter who you see for therapy if that is what you choose to do. There are many different kinds with many different degrees or levels of training. The letters after their name don;t mean nearly as much as whether you "click" with them. Do they seem easy to talk to? Are you comfortable around them? Is the office space comfortable for you?
When I had to look for a new one once, I saw one and went into his office and sat where he indicated. He sat on the other side of the desk. On each side of the desk where file folders piled so high it was like I was looking through a window to see him. The rest of the office had card board boxes all over the place with files and who knows what else filled to the brim. I knew right away it wasn't going to work. I am not a total neatnick, but I can't sleep in my own room if it is too messy. I will get up and straighten it out a bit so I can sleep. I was so anxious, it didn't matter how nice he was.
Unfortunately you have to shop around a little to find a good match. Your pain doc might be able to help if he knows you pretty well. He may have a suggestion or two to try.
Don't beat yourself up for not knowing all this stuff. I didn't and I am sure many more of us didn't either. It comes with experience, but we are here for you and will be glad to help any way we can and answer any questions the best we can. I hope this has been a little helpful. Write and tell us more about yourself so we can get to know you.
