Not much I can advice here other than set your sells at points that you are comfortable with so that when you come back should they execute, you'll be comfortable/satisfied with it.
I am no expert - But stop order could backfire - here's how - some major force (Mr. Bif) drives stock way down for a moment. If sucessfull, PPS goes down a few cents - All stop orders executed. This what I found to be called a "Bear Raid" - happened big time on this stock 07/26 at about 2:30 and I was amazed.
