attempted.. did not succeed

Well done for trying to commute, but also well done for realising early enough that cycling (or driving anything) with a migraine is a dangerously bad idea.

Your next commute probably will be okay, but a backup plan won't hurt. It might help if you keep a small bottle of water plus whatever tablets you take either on the bike or in your pockets, enough money to get you home if you can't cycle, and emergency contacts of people (a trusted cab company if you've got no friends or relatives available?) to pick you up if needed. This may seem like overkill, but if you've got all this with you, the next migraine will be less of a problem.

AFAIK thunderstorms can trigger headaches and/or migraines, but seeing as the attack started after a few miles, it could be low blood sugar or dehydration being the last straw on top of the storm.

For the next migraine, maybe see if you can get a thin black silk scarf? This flat has nowhere that can be darkened enough, and a silk blindfold isn't bulky (even folded over several times), doesn't itch, won't dig in when you roll over, and the darker the colour, the more light it keeps out. It may also be worth getting a v dark pair of wraparound sunglasses to wear when you've got a migraine but can't rest immediately. Sugar + caffeine can also help slow down an attack long enough to get safe (e.g. get a cab or a lift home if poss, failing that, rest as soon as you can). I've found it's best if any painkillers or anti-nausea stuff is taken at the v first sign of a migraine (or it comes back up before being absorbed).

If your migraines are at all stress-related, you can be prescribed betablockers, which you'd take every day. These aren't addictive, and have v few side effects, but they do stop surges in blood pressure, and if these don't happen then neither can a lot of migraine attacks.

It may be stating the obvious, but have you kept a trigger diary? Need to keep track of everything which happens 24 hours and less before each migraine attack - after a few migraines, common factors should start showing. The other thing is, have you been referred to a migraine clinic? Not blaming the GP, but there are a lot of things that a GP is just too busy to know much about.

FWIW, have had migraines most of my life, know my triggers, and have reduced them to approx 6 attacks a year (at worst it was a couple a week).
