I've not taken it (but it's on my list of "maybe to try later" stuff), but am interesting in following along with how this works for you, and also hearing of the experiences of others.
I am taking it too, but don't feel light headed. I am dividing the dose--half capsule (100 mg) in the morning, and the other half in the evening. Maybe you could try it that way?
My capsules (Swanson) are 400mg, I should have searched it better.I've never had side effects from a supplement, it caused quite a big hypoglycemia, I had to lay down or else I would throw up.After 3-4 hours I woke up still in the same situation.I guess I should divide it in half.
