The last time I have a sv* (about a year 1/2 ago) I almost fainted right after I v* I held it together and got myself to my bed and felt better. The sv* was running through my house (my kids had it first) so I wasn't eating/drinking properly the days leading up to it so I think that was the reason. The other time I remember, I was 16, and we were at a spring with my family and some friends. I was really hungry and it was really hot out and I was sitting on a log watching people swing from a rope into the water all of a sudden I felt really sweaty/hot and weak. Next thing I know I'm falling over into the water, I know right, scary! I woke up and hurried and swam back to our boat and ate my lunch and drank a bunch of water. I think my blood sugar got too low or something.
