Silver lining, pah

The good thing about having two ridiculous migraine attacks in the past couple of weeks? Not being able to keep anything down, not even water, and losing 2 kilos because of it.

These attacks are different from the ones I usually have, as they seem to stem from stomach/bowel irritation, with excessive nausea. I wonder if they're due to the Metformin I've been taking. I have another check up tomorrow, must remember to enquire.
