Switching from Zoloft to Lexapro - Need Advice!

I recently switched from zolof to lexapro and I find I'm still a little anxious on the lexapro. But the zoloft made me have insomnia. I also was on Lexapro in the past and helped a lot, but I feel that since having my children, my body has changed so much. And now I'm trying yo find a med that helps. I recently also just purchased the Ritaul pills for stress to see if they help.
