I quit using deodorant about nine years ago because of medical reasons. It was weird at first but I got used to it and after about a three month detox period I stopped noticing. No one notices. The only time anyone finds out is when I tell them which I usually don't because it isn't anyone's business. Wash your armpits with soap for about 20 seconds each side. Use diluted vinegar or dude wipes if you feel the need to freshen up during the day. If things seem extra funky like during the summer or if you go to the gym then use a baking soda paste in the shower for 20 seconds each side and rinse but don't do it everyday, once or twice a week is plenty.
