Goofy question. When we booked our December cruise I went on a diet and excercise program. Now I'm 45lbs lighter and I've noticed (wife has noticed too!) that my sex drive is in over-drive! I'm thinking it's the combination of high protein and multi-vitamins. I just can't get enough and the wife is considering sleeping with barb wire around the vital parts to thwart those early a.m morning attacks. Is this a common side effect to weight loss? Any other guys (or gals) notice this after losing weight?
