Driving home after lifting for 60 minutes or so, I had to pull over because I had the feeling I was going to pass out. I felt great during and right after my lift, but 10 minutes later driving home, broke out in a sweat, numbess in limbs and thought I was going to pass out. The feeling of passing out lasted for only about 2 minutes, but the strange feeling of numbess in limbs and upset stomach lingered for an hour or so. Been lifting for 20 years never experienced anything like this before, same supplements for years, creatine, protein. Low blood sugar? Any ideas would be greatly appreciated...
