Akkilk, I'm on 11 mg. HC per day. I spread it out through the day, 5 mg on rising, 2.5 mg at lunch, 2.5 mg in the afternoon and 1 mg before bed.
My sleep had actually become normal again for 2 months before starting with Lam. I attribute this to my quitting my job and not having any stress, which improved my situation somewhat.
