A colleague of mine swears on taking an appetite suppressant to help him lose weight. He says it’s the best appetite suppressant he took and can attest that he is losing weight from taking it. Since it suppresses the appetite, he now seldoms eat because he always feels full. That is why he always have water with him and drink water often. He even testifies that because he doesn’t feels hungry, he can sometimes feel drowsiness from not eating, and that would be one of his cues that he has to eat.
