I wasn't sure where to put this but maybe some of you guys have experienced this before. This has happened to me twice in the last couple years so I don't know if it's something to worry about but I was in the supermarket over the weekend and started to feel very faint. I started to sweat like crazy and I had to sit down. After I sat for about 5 minutes I was incredibly hungry so I tore open a can of cashews that was on the shelf and ate about 2 hand fulls. Shortly after I ate I felt just fine like nothing had ever happened. My skin was very cold and clammy but I was sweating like a mofo. Any ideas?
