Hi, I am female 5'2", 105 lbs .54 yrs. old, I've had a neurally mediated hypotension for 10 yrs. and chronic fatigue. The only drug I take is one half milligram of klonipin a day. When I have a large bowel movement (which I think is healthy) in the morning, sometimes I get so week I feel like I might faint so I drink sweet drinks and eat something salty to help revive myself, sometimes the weekness lasts for hours and I have to lay down w/no energy. How can I prevent this vasovagul weekness after morn. bowel movement?
