Gotta think about the long term side effects of the smokies too, so it is good to persist with experimentation of alternatives. Hell, even the short term effects, last February, during a real cold spell, at work I went outside for a ciggie, came back in, scarfed down some tea, boom, nosebleed...that was at about 12:30pm, 10pm in a+e, still bleeding, it had been like Carrie in the office, it just didn't stop, two nights in hospital, an inflatable tube shoved so far up my nose it felt like it was pressing into my brain, silver nitrate stiches up the inside of my nose, lots and lots of blood, more blood, and mucus...ahhh, those were the days...all because I needed to go outside for a ciggie, which pulled a blood vessel in combo with the cold, one way, and then had a warm cuppa, pulling it the other way...sweet!
