Does Nicomide affect sleep?

I take Nicomide for acne prevention & have noticed that now I can't sleep. I've been prescribed to take 2 pills a day but have cut back to one pill a day & sometimes even half. In all cases I can't sleep. Is there anything I can do to offset this side effect?

I've been on Nicomide before & like how it works except that then I stop sleeping & am forced to resort to sleep medications. I know this pill contains folic acid & I investigated and found that folic acid can sometimes cause sleep issues.

Any help is greatly appreciated!
