CrystalPalace, it really varies on the person and the situation. Most of us experience detox symtoms and they vary. My first time fasting I experienced horrible symtoms for 5 days straight. It was hell. lol. But I just tell myself that I'm going through detox and this is the process.
It might help if you up your water intake and maybe do a salt water flush to clean out your colon. I know it sounds strange, but it might help release some of the toxins and you may start to feel better. I hope this helps. Good luck!
