Have you explained your job situation to the surgeon? I had to explain in very plain and simple terms what I did for a living to my surgeon before he completely understood. Once he did he said 8 weeks minimum was best because of the reflexes I need as well as strength.
Maybe ask when you can start heavy weight lifting? His answer for that may be different than what he has told you for when to return to work. For heavy lifting my surgeon recommended waiting 12 weeks at least.
Bottom line. Ask your surgeon what they recommend. All that money you paid entitles you to pester them with all your questions.

Oh and I second the micropore taping. I have very good scar results, so good that the surgeon was a bit stunned at how quickly the scars faded. I used the micropore tape for 14 weeks in combination with kelo cote silicone gel, something that my surgeon hadn't seen the results of before. He didn't tell me to use the micropore tape but said I could when I asked him.
