Anyone else experience shakiness in the evenings?

I get colder in the evening and shake/shiver. I usually eat a little something and put on a heating pad or crawl under the covers.

Yes it sounds like ur iron or sugar is low like mine. I have not lost much weight at all. I had my band removed in December 2013 and sleeved March 2014 and only lost 34 pds and gained back 13 pds. Now I've learned I'm battling hypoglycemia. I worked out hard over the past few years watched my fat intake and now I'm told I'm not getting enough fat in and to stop working out. Been battling dehydration for over year. I get headaches and acid feeling from my stomach which triggers headaches. I really regret this surgery. All of them
