I have suffered the odd bout of dizziness in the past (fibro symptom) but after starting lc'ing it became severe, I was having at least one bad bout a day (vertigo - room spinning) I read up on the internet and all I could find was that it isnt harmful as long as you arent losing consciousness (sp?) with it. That did little to alleviate my worry! but it did say the more you worry about it the more it will happen. After a week or 2 it should stop. Now I get just a feeling of lightheadedness now and again and I just stop deep breathe and RELAX thats the main thing I believe, get uptight and you get a full blown attack. It can also be a side effect of meds like diuretics etc. Get up slowly and try not to rush anywhere. Hope you are feeling better soon.
