not a good idea in my opinion, ive heard some horror stories about people trying to lose laxatives to lose weight.

NO NO NO NO NO! Laxatives do not cause any actual weight loss. This is such a myth! People believe that because when they take laxatives they lose all the water in their system that they are losing weight. But they're not! Their weight goes down temporarily because they lost all that water, but as soon as they drink anything they gain that water weight right back (and then some!) Laxatives are SO hard on your system! They dehydrate you and if you abuse them for an extended period of time, your body will start to rely on them and you won't be able to have a bowel movement without them. They also cause you to retain water weight, so you can get edema, which is where your ankles and belly hold onto tons of water and well up huge! Plus, on top of all that they are extremely painful and just plain gross! It's a horrible habit/cycle to get stuck in, so it's best to just stay FAR away from laxatives (unless you are advised by a medical professional to take them for a medical reason!)

that is not a good idea

Laxatives may help you to loos a marginal amounts of weight but it will cause long term heath issues.
