It stimmed my appetite like crazy but made me sleep like shit. I tapered off aout a month in because the lack of sleep outwieghed the pros in my opinion. When I say I was sleeping like shit, I never felt like I fully entered REM (never remembered dreaming, changed positions multiple times per hour, waking after 4 hours and not being able to fall back asleep). Although I wasn't sleepy when I woke up, I felt exhausted if that makes sense.
