Yes! I've just been doing UT for a little over a month, but I need less sleep and eat less.
I often seem to have shallow sleep on UT but I don't feel exhausted when I get up anymore.
When I drink it, I don't feel hungry.
My protocol: At first I just drank mid-stream of first urination after 3am. This week I've drank some more of it until noon. I am a vegetarian and have decided to quit fish and eggs which I never enjoyed much anyway.
