well I can relate to the work place situation. Luckily though there is one bathroom that is further away from our main area and i often use that (it also has a good exhaust fan ;) I'll use the drops sometimes (Coloplast O.A.D. works well). I've also noticed that when i take my iron supplement it decreases the odor and makes my output real dark too. I just got some deoderant tabs to put in the pouch today I'll have to see how those compare.
I think it is Hollister that makes little packets of lubricating deoderant. That would be easy to sneak into the bathroom with you.
Hang in there!
Best of luck
