white oval pill with jmax on one side ## I'm 51 and have the flu. I took j max last night, hoping to get some relief, and had unusually vivid dreams. During one, I woke myself up when I kicked out hard enough to fall out of bed. Then I had another where I dreamed I was in the bathroom and ended up actually wetting the bed. My third dream was that I was again in the bathroom, on the toilet, then catching myself, afraid I was dreaming and would wet the bed. I looked around to check, saw that I was indeed in the bathroom, and proceeded to use the toilet. Unfortunately, I was dreaming, and this resulted in me wetting the bed -again - something i've never done as an adult. What is in JMax that would cause such vivid dreams? I don't think I'll be taking it again anytime soon.
