Morning unless I got sweaty and dirty at work or something. I don't ever stink, I've gone 3 days no shower consistently doing overtime at work(sleeping at work, whilst getting paid). What I have found though is when I eat a lot of junk and drink too much I get stinkier much faster. When I eat clean I don't ever stink even when I sweat. There are people that shower once a week and you spent even know it. On the other hand there are people that shower twice a day and smell like the under side of a fat guys moobs.
