If you just have 2-3 miserable days without by day 4 or 5 you should start to feel normal without it. 15g a day isnt a massive dose either. I long term take up to 2.5g 4x per day, and makes my quality of life far better and Im exactly the same I have no mood to play my games etc before doses but while im taking I love to play. I have codeine on prescription as I have serious chronic pain so every month I switch to codeine for 2-3 days which give simular effects and give same motivation, then
