"I am in need of drastic personal changes regarding diet/exercise". This kind of thinking scares me. What's wrong with gradually moving towards a more balanced lifestyle, taking on one hurdle at a time? Whatever happened to eat well, sleep well, exercise? Why this sudden urge to 'change everything' from one day to the next? Why directly switch to vegan when 'eating less meat' would be a good start? Do you want to get healthy for real or just feel the satisfaction of "living a healthy lifestyle"? Sorry if I'm a bit harsh, but I see far too many people suddenly "switching to diet X" & destroying themselves in the process. Go easy on your body.
