I've only eaten for 2 days, and my chest hurts a little and my stomach swells. They overcame it and said, maybe it's my poor health. Their medicine has strong efficacy and high concentration. Let me take it once a day instead. I ate it after dinner yesterday. I feel nothing, but it seems to hurt if I eat it on an empty stomach. I don't know. I'm trying it for 2 days to see how it works ~ now the diet pills will bring something, chest tightness, chest tightness.
