When I was ten (14 years ago), I was on a plane in the smoking section for about 15 hours. From then on, I think I smell cigarette smoke for long periods of time. When this happens, I can't smell anything else, unless I really concentrate. I feel like I am in a stuffy room filled with smoke. Every time I inhale I feel as if I am breathing in smoke and tastes it a bit.
When this happens and I feel like I need fresh air, this is usually when I realize that I think I smell smoke. This condition would go on for 2 weeks to 2 months. Then all of sudden, it would stop. And when I smell smoke for more than a minute or so, something would trigger and the cycle occurs.
Does anybody know how to stop this? Does anybody have any resources on this topic?
