I use Oster's OB protein and eat it when I get up two mornings a day. I just started taking this medicine yesterday morning. I also watched my friend lose more than ten kilograms a month after using OB protein, so I was very moved. After taking this medicine, I feel flustered, my heart beats faster, I feel dizzy and thirsty, but it's okay to drink more water. I also feel snoring and diarrhea. But my friend's weight loss effect is good, so I still insist on eating, hoping to lose weight.
