Zoloft can take about 6 weeks to take full affect which is probably why your were given the Klonopin too. The Zoloft may be causing your problems, but it could also be that you haven't given it enough time to take full effect. My doctor gave me Clonazepan (sp?) to take 2x/day for 6 weeks so my Zoloft had time to work. You might ask your doctor about how often you can take the Klonopin...you should let him know you feel your anxiety is worsening because he may want to try something else. Good luck!
I had to try several meds before my docter and I found a combo that worked best. Some of the meds caused more anxiety just as you describe, and like you I tend to have more anxiety at night than at other times during a day. Zoloft didn't work for me. Neither did Zyprexa or Effexor. The symptoms are best controlled for me with Lexapro and a small dose of 24 hour Xanax at night. Just don't give up because one medication isn't working. Keep trying until you and your doc get it right. And one thing that I found out the hard way is that you definitely need to see a psychiatrist to regulate these meds. Your regular family docter or internest is not gonna do the trick. :-)
absolutly its normal for it to get worse before it gets better. or, its a common effect. Give it another week, if things dont start to get better i would contact your doctor. This happened to me when I first started Lexapro, my anxiety got really bad for about a week or 2 before it started easing out. Then when I switched to Pristiq my depression worsened for a couple weeks. It is normal for antidepressants to do this. So, just push through these next few days and i hope it gets better for you.
I wish you well
