When are you taking your dose? I have always done mine at night an hour or two before bed, so that it has time to get in my system during a time the effects aren't a big deal.

I recall a calming feeling in the first few weeks and I did feel a bit loopy with headaches. I wound up at 400mg to reduce my extreme depression and self harm thoughts from a daily occurrence to a couple times a month. The worst and only side affect now is a foggy mind, I have a hard time recalling things quickly.
