The plan is not at all an option to smoke through a water tank, it is very expensive and there is almost no effect. Buy a simple 0.5 plastic, make 3-4 buns out of the plan and make them for parliament silver, and this is a real thrill
If you want to get rid of a bad cough, then no way. At the moment, you are most likely going through a period of adaptation of your throat to heavy smoke (with the plan it will always be like this. "I don't jerk off at all. I have a girlfriend. And I don't watch porn. Never"). And in terms of technique - nothing complicated either, just lift as slowly and smoothly as possible, and everything will be fine.
No sacred secrets, nothing supernatural that will turn your mind around will not tell you on this topic. You just need experience. Although, is such experience necessary at all? You decide for yourself))
