I was the same way when I started the 5 mg. Actually for the first few days I was a nervous wreck ;-). Once it dawned on me that the side effects weren't the nightmare I envisioned, I settled down a bit.

Of course, now I'm a nervous wreck worrying about upping the dose in two weeks!

Good luck with starting; I bet it will be much easier than what you are imagining it to be!
