I ordered the Nature's Acai Berry Supplement and was excited when I got it in the mail on Saturday. I waited to take it on Sunday because I had a late start. So on Monday, I followed the directions and tooks the pill 20 minutes before I ate breakfast. The only thing I had with this pill was water so my stomach was empty. So about 10:30 a.m. I ate my breakfast and about an hour or so, I started feeling nauseous and my stomach started hurting. I was really queasy after 12 that afternoon. So I called the Post cereal company's toll free line and made a complaint with them thinking that it was the cereal that got me sick. Anyway, it was time for lunch, so as stated on the bottle to take it 20 minutes before lunch. That's what I did. So I ate lunch about 4:20 or so, and about an hour later, the same thing happened. I was in pain so bad I was in bed by 5:30. I couldn't sleep, it felt like I was having an anxiety attack, I had a funny taste in my mouth. I just threw the bottle of pills, and the cereal away because I didn't know what was going on. I'm tired of being dupped into these rip off products that only want my money. Today, I feel a little better than before, but now I am cranky, I am very snappy with people, I don't want to be bothered. It's like I'm coming down from a caffeinne high, I still have a funny taste in my mouth. I'm hungry, but can't seem to eat anything. I'm really disappointed because Oprah and Rachael Ray, and Dr. Oz are standing behind this products. I should have know something was up when I realized how much caffeinne was in these pills. NEVER Again!!
