Hey, Sam!

Three thing I can think of, off the top of my head--

1. Yes, induction CAN be an energy drain. Give yourself a couple more days, sleep it off, and see how you feel.

2. Are you supplementing at all? You need to at LEAST be getting in a multivitamin every day. I highly recommend Atkins Nutra-Packs. They come pre-packaged with about 7 or 8 different types of vitamins in one convenient little pack. You take them all, then you're good to go all day!

3. Check your protein consumption. You should be getting AT LEAST 150g of protein a day, even more if you're exercising!
