I actually did the same thing back in 2003. Back then I went from 304 to 197 pounds in six months doing pretty much the same routine I'm doing now (but the black coffee and dark chocolate is a new twist). Then I stupidly put it all back on over the next 12 years by bringing carbs back into my diet, eating bagels, pizza, breads and other high carb foods. I hope I learned my lesson for good this time. Excess carbs is bad. Even the "healthy whole grains" that the gub'mint tells us we should have 6-11 servings a day of in their stupid pyramid.
Your weight loss before and now is very inspiring. :) Must feel really good to be back on track again!
Did you ever have trouble sleeping? A friend of mine gets terrible insomnia. Wish I could recommend something that would be beneficial. Does the dark chocolate help you to sleep or does it just cause the vivid dreams?
