You know staring at the bog never works for me...I think being in the place where I should throw up relaxes me a bit because I don't need to run for it. Hence when I throw up I'm in the wrong place and horrendous amounts of cleaning follow.
I hate this feeling though, its awful, I'd just wait it out until it came naturally, if you need to throw up that bad it will happen eventually.
Never thought I'd say this but I hope you puke
