Well I have gotten a lot of really um....interesting, advice lately.
My boss actually has a medical degree yet some of the things she says makes me question her sanity. Such as the no breakfast, lunch (whatever come from the uni), dinner an apple max diet plan. She's also modified it to skip the apple and just add a glass of water for dinner, and if your really hungry go to bed. Breakfast is miles on the treadmill. She looked at me today and in the most serious way said, "being hungry is great isn't it". I hate with a passion exercising (my short attention span is the main reason) so she told me not to exercise! I force myself on a daily basis to do 1 hour of exercise, but apparently I can skip it and just cut my lunch in half! With her as my example I'm glad I picked law school over medical school!
I've heard of spitting in a cup, but that's used normally by wrestlers who need to make weight, they gain it back as soon as they are done weighing in! Not a long term solution! The second you drink a glass of water you gain it right back!
