You might try burning energy when your awake. I only sleep for 4 hours unless I mentally fatigue and physically fatigue myself then I can get 8 hours. Also you should always ask doctors before taking any medicine. Not those stupid clinic bastards, but private doctors. Reason being clinic doctors need money so they will most likely figure out how to milk it and fuck you up for their long term goal. Private doctors have all the money they need so they will do whatever it takes to get you the hell out so they can continue masturbating to the pictures of hot chicks they stash in their medicine box.
