When we started PB, my wife and I both suffered with lethargy, headaches, moodiness, decreased sex drive, and just an overall unpleasantness for about three weeks. We are 6 weeks in, and I am waking up on my own without my alarm most days. I feel energized the second I wake up. No headaches, no energy swings, no moodiness. Definitely was the carbs! We ate a ton of carbs prior to going to PB, so we attributed the length of adjustment time to our dependence on carbs.
So far, I have lost 19 lb (262 to 243) and wife has lost 10 lb (140 to 130) since beginning. Wife still cheats here and there, but we are really losing weight effortlessly. I am ashamed to say, but we haven't even been exercising. I know if I can kick that into gear, the weight will fall off even that much faster.
I can do all things through Christ who strengthens me. Philippians 4:13
