Migraine...Here we go again!

I went to a migraine specialist on Friday. He has prescribed a vitamin medication for me and he also gave me something to put between my teeth and clinch down on when I get a migraine. Of course I didn't feel to well yesterday so I didn't pick up the medication. Just my luck, I woke up with a migraine today and I wasn't prepared, no medication and no teeth clincher with me. I've been helping my Mom house/dog sit for my brother and sister-in-law while they are on vacation. I do have my other medication with me, my vicodin and tylenol, so I took that. I'm able to handle the pain a bit better now, but the vision problem is what's really frustrating. I also get nauseated when I'm having a migraine, I try and keep from throwing up, so I lie still until it goes away.
The migraine doctor also said I should go in when I have another migraine and they will put me on some oxygen. I tried that with one of my other pregnancies and it didn't seem to help, so I'm not sure I will even go in and try it again.
