I've had a very short temper since starting on the ring 6 days ago. On the first and second night I felt very weak and tired and was nauseous for some time. Every time I would try to stand up the room would spin and I would almost pass out, and when I would sit I just felt drugged. I had crazy mood swings that made me feel like I was bi-polar and my limbs kept going numb. These symptoms have subsided for the most part, but I just want to make sure I shouldn't be worried.
