I am also a nic weenie (as I like to call people like us) but it will improve a bit with time. How long are you smoking the Match 20? There are some light tobaccos that do fine for me if I keep it under 30 minutes but if I smoke them to 45 minutes or an hour I'll start to feel it.I definitely have a low tolerance. Not a former smoker just started cigars recently for relaxation. But they are too expensive and too long of a smoke for me so it's a waste.
Choose to try pipe tobacco since it doesn't taste like shit if it goes out and cost is a lot more friendly on the wallet!
So maybe the nicotine is it. Since my tolerance is probably extremely low and I do tend to be sensitive to substances because of anxiety if that makes sense.
