i've been trying to assimilate the information in this great thread. i'm going through a major setback with dizzy spells and vertigo that's lasted so far for 3 weeks. it started after i ate some pastries--i'd been avoiding sugar and all gluten for months. for many weeks i'd also been eating much more animal protein (eggs, fish, and chicken) than i normally do. for most of my life i have been a lacto-vegetarian. i've always suspected that i had blood sugar problems (along with a sugar addiction), but in these past weeks i seem to have crossed a threshold and it seems much worse. several times in the past weeks i ate an orange by itself first thing in the morning while i was waiting for my cereal to cook. i immediately got dizzy. that never happened before. another time i ate an orange with a meal and didn't have a problem. some days i got dizzy after every meal. it was totally confusing to me, because i was eating different things at each meal. then i started to feel really weak, not only physically, but emotionally and psychologically as well. after talking to a friend who is a nurse and who has hypoglycemia, i cut out all the fruits, dried fruits, and fruit juices, cut out milk (apparently it has a lot of sugar in it) and milk products, and concentrated on complex carbohydrates like whole grains and beans. i felt much more steady, and if i was dizzy i gradually got better while i was eating. but then i'd be dizzy and/or hungry in 1 1/2 hours or 2. so then i started to eat smaller meals more often, which seems to work. it feels like i am controlling the dizzyness somewhat by eating this way, even though i am still getting dizzy sometimes and have a lot of fullness in the ear. i'm trying to figure out how much protein and/or fat (and what kinds) to eat with the carbohydrates. it seems that, whereas before, eating was a joy, now it has become a chore and a puzzle to figure out for surviving. (i hope my attitude gets better! lol) the past few days i woke up around 5 am and realized that i really needed to eat something quick. it wasn't that i was super hungry, but i felt that if i didn't eat soon, i would get weak and then dizzy. it all seems kind of overwhelming to me, but i do feel a little stronger. i was feeling like i was on the edge. i guess i just have to keep experimenting to see what works the best. a lot of the recommendations you see for hypoglycemia in books and on the web are contradictory. i hope i continue to feel stronger.
