Jo, I have the same problem. We both started Induction on the same day and weigh about the same, so I'm interested in the answer! I usually feel great in the AM and start getting tired (may even have a very slight headache) in the afternoon but feel great again by evening. Don't quite understand all of this yet.

I don't know if there's any connection, but I drink my water much better in the AM and tend to slack off in the afternoon. If I don't watch it, I could drink ALL my water before lunch! I'm trying to space it out better. Maybe that will hold a key.

BTW...welcome! Best wishes to both of us!
