yes superman, this has happened to me. I know what you feel like. You usually get used to your own smell, but then this different smells comes out. I used to just smell my cloths because it wigged me out, it just didn't smell like me. At one time I would just take a deep breathe and I could feel the ammonia in my nostrils with a slight burn, this had nothing to do with me sweating.
I just got used to it, then one day after playing hoops, I noticed that I sweat less and that I did not have that ammonia smell anymore.
I have no idea if it was because I was doing parasite cleanse and the little buggers were dying, or that I did all the other cleanses and that fixed the problem, but it just fixed itself and went away. I've seen that all the weight lifting products usually have the ornithine and arginine in there anyway, so take some of those and see if it helps. LIke any natural healing, don't expect results right away, be patient and don't get frustrated
