You are wise to want to start your anti-depressant at a low dose. and increase over time. Zoloft is an excellent AD. With Zoloft, 50 mg is considered the lowest therapeutic dose. If you are going to try Zoloft, I would recommend you start off with perhaps 12.5 mg. After 7-10 days, increase to 25 mg. Another 7-10 days, go to 37.5 mg, and then up to 50 mg. This helps to keep start-up side effects away. Just so you know, Zav, most people that I know that are on Zoloft, take 100-150 mg for good results, and I have one friend of mine who is doing well on 200 mg.
You are welcome to ask me any questions you like, Zav. I take two anti-depressants, Remeron, and it just so happens I was started on Celexa some six months ago. I have been on the Remeron for some 4-5 years now, but last year aspects of it stopped working for me (Remeron is notorious for doing this), so my psychiatrist started me on 20 mg of Celexa. The combination has worked extremely well for me.
With anti-depressants, there is no telling which one will work the best for you; it is a matter of trial and error. Some anti-depressants are more stimulating than others. Wellbutrin is a very stimulating AD, good for depression, but I sure won't recommend it for anxiety disorders. Zoloft, Celexa, and Lexapro are good for anxiety and depression.
Let me know what you decide and how things go for you.
As always, the very best to you, Zav!... Chuck
