My last chance...Day one

I'm only 20 years old and i weight 262 lbs. Honestly speaking, I'm on this for a little of both reasons...I do want to lose weight and I feel if i have the will power to do this then i dont have to get the gastric bypass (stomach stapling) surgery that i was going to get. This is my small step towards leading a healthier life. I know the risks associated with obesity and i'm not trying to die early of complications cuz of my weight...I want to be healthy and enjoy life. So I'm planning on doing this cleanse for 30 days...although being my first time doing this i might have my sights set too high, so if i feel fine within 10 days, ill keep going. Unfortunately, not being able to eat is like being told not to touch the red button...its all i been thinking about. But i cant have that little will power and quit after just one day, right?? I guess all im looking for is encouragement. I have a little headache which is nothing i cant surpass. I guess ill use this as a record keeper, if anyone is interested in my struggles. I did the detox tea last night, then the salt water flush (which by the way has to be THE worst tasting thing in the world) in the morning and been drinking the spicy lemonade since...only drank 7 cups since i am in it for wieght loss too.
