Ok, I'm starting to get a little scared. I drove to the bank today vaping the whole way (had the 16mg RY4 in). Well, after about 15 min my throat muscles felt like they were tightening up/cramping. It would tighten for about 20 secs or so then go away only to come back. I laid off vaping till a few min ago and now it's doing it again. You know when your leg/arm muscles gets those weird twitches? That's almost how it feels, but lasting longer and with my throat . It's in the center where guys adam's apples would be towards the front. Any suggestions as to why this is happening would be appreciated. It feels really weird (like my airways are tightening) and I just want to make sure I'm alright. Thanks
