The vaporizer I use has a large enough bowl that I can get 4 total vapes (3 minutes each) out of each bowl, so it will last the whole day. Plus, I'll do a vape at the first sign of an ocular migraine - seeing auras, which will stop the headache right way. Besides, I take 3 different eye drops 3-6 times a day, which help, a little.
Here in Michigan, it can take UP TO six weeks to get your card in the mail, but if you don't hear from them in 21 business days, you are presumed legal. Also, technically, dispensaries are illegal in Michigan, courtesy of our Supremes, but that is being widely ignored. Some cities have passed ordinances allowing them, a few outlawing them.
The Mayor of Lansing, Virg Bernero, has ordered the local police to leave them alone,
so you can find them on every side of town. They're not all equal, though. A couple will make you feel like you're doing an old fashioned drug deal, I avoid them. But there are a few that actually treat it like you're there for medicine, those are my favorite. There's one "el primo" place where everything is tested, pre-bagged, and more expensive, they're the place to go to for advice. They have a Doctor who does certifications every week. The varieties of product are endless, and change daily. Several places offer medibles, some don't. For all our state's backwardness, the people have spoken, and are choosing to ignore our happy drug warrior Atty. General.
I wish you the best of luck, Laura. I can honestly say the CBD strain has helped me more that all the drops I have to take. Hopefully, it will work for you, too.
