I have started this medication after having bad side effects with the last three I tried. So far have been on it for two weeks and have no side effects - but no positives either 😞 I had thought this one took effect but I found out it takes about 4-6 weeks to notice anything so I'm going to wait another few weeks before I switch. Btw I didn't notice any differences with my sleep but I have five kids so sleep is a long distant memory 😉
