I found the vitamin regimen to be very effective at lifting the brain fog, its definately worth a try. I've been taking the vitamins for months now and the fog has dissipated. Actually, it only took a few days before I started noticing the change. Diet is important too. I'm cutting out processed sugar and eating more fresh vegetables, berries and nuts. All that is helping with forgetfulness and concentration issues.
Best of Luck!
