have to tell you about something that was an occasional huge pain in the keister for me --Ocular Migraines. You know, that weird bolt of light that floats around in your vision, making things like reading, watching TV, and driving darn near impossible, until they pass, usually after 20-30 minutes. Well, when CBD came along, I was curious. The tincture was already helping with my back pain, so I decided to try it one day when I got a huge ocular migraine that was blocking out about 3/4 of my field of vision. I dropped a 33mg dose under my tongue, waited about a minute and swallowed. In about 4-5 minutes, everything was cleared up! It was awesome! I found out that a gummy (or sometimes two)will work too, and it's much easier to deal with than the tincture, especially when you're out somewhere when one hits. I try to carry some Tommy Chong Nano Gummies with me anytime I go out now, just in case I get one of those ocular migraines when I'm out driving or whatever. Nothing else has ever helped before except time, so it's GREAT having something to knock them out pretty quick.
