Tips to improve technique of 'chasing the dragon'?

[beena]

SWIM has been chasing the ol' H on foil tonight, but finds it tricky to catch the smoke and is feeling like a dumbass cos SWIM hates to waste. SWIM is getting some (but not much) effect and can definately taste it at the back of her throat but she can't help feeling she is wasting a lot more than she is getting. Are there any tips SWIY could give SWIM to improve her technique and/or maximise intake.
