Dear Sir,
I'm not sure if this is the best forum, but it seems the closest fit. I'm a 30 year old British guy, 5'11", 175lbs. At the moment I'm working overseas, and likely to be doing so for at least the next 6 months.
For a few weeks now I've been noticing wafts of what I can only describe as the smell of Ammonia. I cant be sure where the smell is coming from - it's quite obvious if I breath in really deep through my nose a few times.
