Query: Not what I expected

To "test" how my body responded to this product, I began by taking 1 pill per day after a meal with water. The first day my heart rate was slightly increased, I felt a little light headed, and I got the same "high" feeling that I normally get whenever I've drank a good amount of coffee. I took 1 pill a day for a week, and felt full after small meals and didn't desire much food. But, on the 6th day, I began to have trouble breathing. I felt like I wasn't getting enough air. I felt like I had to take really deep breaths to feel better. I discontinued use and still had this strong sensation for about a week after stopping. As I'm writing this, it's the 2nd week after stopping taking this and I still feel some restricted breathing.I know everyone responds differently to different things, but I can't say from my experience that I would recommend this to anyone.
