I got one of those 3M Airstream respirators... I haven't had it for too long (maybe used it ten-twelve times). It is great... the only problem with it is that when I use it over an extended period of time it really kills my neck. I usually turn for a couple hours at a time and when I get through I am kinda sore. After a little bit that soreness goes away, but I am just wondering if this is normal and if I just have to get used to it or if something is wrong. Anyone else have this problem? Any comments would be appreciated... thanks!!
