Rudy said that if it was oxygen deprivation you would be yawning... but that isn't necessarily true because you can't yawn while you are taking a hit. and the body will try anything and everything to get oxygen to your entire body... which usually includes shaking since it increases blood flow.

So like I said, just take it easy, don't take monster rips and don't hold them in more than 5 seconds. Exercise and a good diet will certainly help with the circulation and blood pressure problem, but either way if things don't get better you gotta go see a doctor. you never know when things like this could be much more serious than they seem (i.e. if your circulation is being forcibly slowed by a swollen gland or blood clot - which I highly doubt is the case lol)

Just be careful and take good care of yourself. That's the best advice I can give.
Well thank you for the advice, it sounds good. I didn't know about the 5 seconds. Nothing like I described has happened since I posted. Breathed deeper, without emphasis on holding it.
Actually, I do have a good vaporizor, and it gets killer rips, I definately have it turned on too high, there is too much vapor and I cough a lot. But I love it once in a while. I am pretty new at it.
