Can Clonazepam Be Taken Along With Zoloft As A Sleeping Aid?

Hi, my name is April and I just started back taking Zoloft after being off for 6 months. Now I'm feeling panicky and sick at the stomach! Can I take clonazepam with the Zoloft to get some sleep? Also, how long before you think the Zoloft will kick in at 50mg. I thought it was already in my system so I wouldn't have these problems again!
