I've been on doses from 1800 inpatient to 150 tapering down over a year. It made me zombie like and very tired at the higher doses. Less tired but still sedated at lower doses, and some cognitive dulling. As a result of the tiredness and sedation I gained 15lbs. Also gave me acne. I did not have any tremors and it flattened my mood nicely, didn't care about anything and it was impossible to ruffle my feathers on it. It also pulled me down out of mania nicely.
