I'm down 10 pounds in 11 days, and I've not been hungry on the program. In fact, one day I had to remind myself to eat as I wasn't hungry or feeling empty at all. I take the pellets three times a day - usually 7:30 am, 12:15 pm, and 5:30. No after taste has been noted, and absolutely no negative side effects. Would like to see more weight loss as my friends who are using drops, but still I'm seeing results. I chose pellets because the drops must be refrigerated, and I'm not often home to do so.
