Thanks for the replies. I am now on day nine. I was really anxious on days 6-8. It was really terrible, a feeling of doom, anxiety, sweaty palms, insomnia. I didn't get to sleep until 2am yesterday morning, my mind was racing, I had restless legs, it was awful. I started thinking that maybe the dose wasn't high enough, as I seemed to be ok for several hours in the morning after I took the lex, then by early evening the anxiety ramped up.
