I recently started taking optimum's opti-men multi-vitamin. I take it first thing in the morning with my breakfast. I have been taking this close to a week now and every night I have had insomnia. I go to sleep fine but wake a few hours later like it is time to get up when in fact I have several more hours of sleep left. I have a hard time getting back to sleep at this point. Traditionally I have no problem sleeping from when I put my head to the pillow until time to wake up. As far as I know this is the only new change to my diet.

Has anyone experienced anything similar with this product?
