Hopefully someone can give me some insight. I'm on Day 9 of P3, and my weight is stabilizing great which I'm happy about. However, I'm getting terrible headaches and not sure why. I never had a headache during 42 days of P2. Has anyone experienced this in P3? Did you find the cause? I thought it might be the cheese or almonds that I added small amounts of. However so far today I've not had dairy or almonds and still have an aweful headache? Any suggestions? Thanks.
