Please do post how accutane helps your oily skin. I am about the same age with pretty much the same issue; overly oily skin. I'm still weighing the pros and cons with accutane. I completely understand your internship experience; I had the same deal only I worked in an electronics lab with protective goggles. Very annoying on an oily face.
Yeah, yet another thing that was ruined by acne. On top of it my boss sat me down in his office and gave me a lengthy lecture about how I need to go out with the others after work or I'll become isolated. He thought I didn't want to go because I saw myself above it all and was like "Now I'm gonna talk some sense into this kid". And I sat there and said nothing, because I didn't want to tell him about the acne. I didn't like him very much so I didn't want to discuss such a personal topic with him. *sigh*
Yea it happens. I've learned to blot my face on breaks using the paper towels in bathrooms when I'm on break or lunch. Have you tried that? It makes a pretty big difference, as it gets rid of the excess oil with minimal effort.
Good luck with accutane; it is slightly risky but no where near as bad as everyone says it is. I have never taken it but I've researched the hell out of it; and the numbers show that the majority of people just have minor issues like dry eyes and lips, nothing really too serious. Of course the horror stories make it to the internet though LOL. Just stay alert for potential issues and make sure you have someone to talk to if you need it.
