I dislike socialism and overpriced medical care as much as the next guy, but dude, relax a little. Breathe in, breathe out. Think about Jesus as a baby. Now an island with a cool breeze and sunny skies. Now think about how much God loves you. Now a rainbow. Now, relax.
A few nice slow deep breaths will do wonders.
That first hit off a cigarette isn't so much the drug rush, as it is a deep breath held and exhaled correctly! Ex smokers and current smokers try it. OK even non smokers try it, pretend you just sucked in a mouthfull of cigarette smoke, inhale deeply, hold it and exhale a little slower controlled.
