I've tried Hoodia. It takes about 3 days to kick in. I needed to take it at least twice a day for it to be effective. After the 3rd day it worked really well. I'd eat just a few bites of food and feel satisifed. It also seemed to take aware those hunger pains, when you haven't had food for several hours. I go through a month supply in half that. 60 capsules from GNC only lasted 20-25 days for me.
It works but takes a few days to really kick in. My usual dosage was 2 capsules in the morning when I wake up, 2 in the afternoon and maybe 1 at night before bed. All depending on how hungry I was feeling.
