I got worse and worse, too, and was only taking 1.5mg. I stopped sleeping for a month.I've been taking it for a few months at 4.5mg. Effects not all neg but over time I got wose and worse. Now I stopped it and already doing better. Will start with very low dose soon. Probably only small window that works.
