1) You'll feel like your having hot flashes.
2) Terrible smelling pi$$. Something like you've never smelled before,and very dark.
3) You will in general stink....breath, body odor.
4) Your appetite will be nil...nonexsistant.
5) sleeping at night will be difficult at first, as your body adjusts it should get better.
I can't think of anything else. Good luck.
