yeah foil is the worst. the first time ever i had my own weed i got it from a co-worker who gave it to me in exchange for staying extra hours and working his shift so he could go home. he told me to use foil since i was so inexperienced and obviously didn't own any pieces. let me tell you, foil is very ineffective, unless i was just stupid and doing it wrong.

i would take everyone's advice and quit the foil. maybe cut back a little on smoking all together or try and get some meds for it.
