I used to the the pill with no issues. I was on it when my pain got bad and a couple of years back I actually stopped taking it to see if it made things better. It didn't. I've tried to go back on it a few times but get horrible side effects: so tired I literally fall asleep during the day, nausea and incredible hunger. I was not that bad pregnant! It gets worse the longer I stay on. I've only lasted to 7 days as it was so bad I couldn't leave the house or take care of my children. I've tried several different pills, some with less oestrogen. Does anyone know what would be the cause of this?
