Out of all the forums I read and hang out at, you guys seem to be the best with health issues. I'd appreciate some advise on my current situation. I've been sick for a little over a month. Not with the same thing, but a bunch of smaller things one after the other. I've never been a good eater, so I don't think my immune system is in the best shape right now. That's probably why I kept getting sick. Two weeks ago, I went out for the first time since before all of this started. I went on a hike a little under five miles. At the time, it felt great to get out! But then there was the next morning... It was Sunday. I had church. My morning was pretty normal. Didn't feel bad at all. Actually, I still felt great from the hike. I sat down in church, and when I got up to sing - I felt a little dizzy. At first, I thought it was just a head rush. So I waited. It didn't improve. Steadily, it got worse and worse. At one point, I felt like I was on the edge of passing out. I panicked, and my heart starting racing. Seriously - never panic. A racing heart makes it much worse. It wouldn't stop, so I had to be driven home in the middle of the service. It didn't stop after that day. Every time I get in the shower, I get dizzy. It also happens when I stand still in one place for too long. I've found that it happens less after I've drank V8 or something sugary. Since it didn't happen until after the hike, is it possible that I'm low on something? It's crucial that I get this straightened out before Sunday. I'm not going to miss our Easter service. I really don't have the time to go to the doctor. Do you guys have any ideas about what's going on and/or suggestions on how to improve it? As I said, I feel much better after I drink V8 or something sugary. Would caffeine help this, or should I avoid it?
