Good morning, I am a 49 year old woman that has had gastric bypass about 3 years ago. I am getting light headed. Most of the time it is in the morning but not exclusively. I have tried not eating sugar and eating sugar, coffee and no coffee, none of those seem to effect the problem. It is not a constant but happens about 3 to 4 times a week. Do not effect my ability to walk or think, my speech seems sluggish during these episodes some times.
