with starting up the med again after being off some time, and the sleep issues that arise, wondering if i need to get up earlier and take it earlier. for me, i'm thinking it's lasting close to 16 hrs. does anyone know how long it works on a daily basis???
i have been on 37.5 milligrams for a month now. One pill is in your system for 12 hours.
