Hello Chompers!
Yes this has been discussed many times here, but I think with all of the new faces, we need to revisit this topic every once in a while. I'm going to throw my two cents in quickly here, and let the rest of the members have their say.
Probably the best rule of thumb that I learned from this site, is not to share with others what you are being scripted and how much. The general public will never have an understanding of this, and it can at times invite some distrubing comments or work related repercussions that may not end up in your favor.
Even if you try to keep it a secret, working in a close envioronment can be a problem, for the simple fact that your eyes may be a dead give away to those around you. Most of the time, when taking pain med's the pupils will be what I call "Pinned" or constricted down tight. This may be indeed the difference of what they are seeing with you. Maybe?
You are right that it is not anyones business, so becareful shareing the fact that your on them. Also many company's will frown upon and have policys in place, for saftey reasons. I think you may be looked at, as a lability in the work place as well....Just be careful!
