I'm currently on it. It takes a lot of mental willpower, I'm not going to lie about that. It's worth it though, you don't feel hungry, your cravings go down significantly - anything you feel cravings-wise is pretty much in your head (you want the taste of something, you are out with friends, etc), but even that goes down. It works! Some people choose to be monitored by their doctors to make sure nothing happens, and from everyone I know who has done that, there hasn't been any health issues - the reverse happened actually, and a lot of people were able to get off other meds or reduce usage. Just go to orientation and you'll understand
