Summers approaching, and I am going to be spending time at a water park soon. I am super self conscious of my body, since I am about 250 lbs. I am going on this 3 day cleanse thing where you drink water infused with cucumber, citrus and mint. You don't eat, just drink. I am also taking dulcolax, since I already have problems pooping. I will be doing the 3 day cleanse, eating only raw fruits and veggies the next 4, still drinking the infusion. And then repeat the following week. I am hoping to drop 20 lbs. Is this bad? I seriously have 2 weeks and don't know another way.
