Well ladies, feeling much better now. Headache, nausea gone. Been taking zopiclone at night. What a difference. I'd been surviving on about 3 hours sleep per night due to various reasons for several weeks. My body obviously decided enough was enough. Pills have given me a chance to catch up with myself. Fingers crossed it continues. Halving tablets tonight, so hope I sleep.
However, I was very interested in the AIW migraines.
