I just went through the same thing.....my da vinci was 4/8. Started going back to work last week, but, like Lawink says, only 1/2 days as I was really tired about 1:30. I'll work 1/2 days this week and then return to a somewhat full time schedule next week.
I also can wear jeans every once in a while so I took an extra pair, but didn't need them.
Only other things are a big smile and great attitude, which it seems like you have already packed!!!! Your friends will be glad to see you back.
