So here's a story:
Today, I'm laying in my recliner, trying to read a chapter for my Software Design class this evening. I feel sleepy, so I try to catch a nap. I slept about 30 mins off and on. I realized that I needed to use the bathroom, so I hopped up and went to handle my business. Sometime during that process, my heart started beating fast and I realized that I suddenly felt horrible. Next thing I know, I'm trying to figure out where I am. It takes me about ten seconds for my vision and senses to kick in and tell me that I'm laying with half my body in the bathtub, arm wet, head and neck hurting. I pull myself up and stumble back to the recliner.
Now, clearly, I passed out. I'm assuming that I just got up too quickly, altho I don't remember the experience of a head rush really. I don't remember anything much. For anyone with experience with this kinda thing, this is nothing to worry about, right? For the record, Its about 5.5 hours later and I still feel kinda lightheaded.
