Hello, I just had a quick question....I had a weird episode last night. I woke up feeling strange,,a bit light headed, weak in the knees, nauseous and severe dry mouth. I had some milk and then layed down. I then experienced some shakiness or tremors, like shivering that won t stop for about 20 minutes or so...then the eposide subsided. I was thinking I either had low blood sugar or low blood pressure?
