Im not going to tell you not to do it but that is extremely dangerous and unhealthy. Enemas alone is extremely unhealthy if used for anything other then a medical reason. I hope you are at least eating more the 1200 calories a day otherwise you are starving your body and will cause it to start shutting down and will end up losing muscle instead of fat. I have done tons of research over the last year. A person should never drop more then 2 pounds a week, if they do their body will not be able to keep it off and will gain it all back plus more once the diet is over. The only healthy way to drop weight is to eat three healthy well-balanced meals a day, three healthy snacks a day. Eat more fruits and veggies, drink at least 64 ounces of water a day. And moderate exercise. If you want to keep your weight off and be healthier please dont 'diet' and do anything drastic like this or unhealthy and damaging to your body. Also join the cafemom group 'healthy weightloss' they have alot of weightloss experts that can offer advice. Im just saying this all cause I know you want to have children and I would hate for you to do anything that could make it even harder then it already is.
