[spoiler]Ok[/spoiler] When you go into surgery, you get knocked out for at the most a few days. It took me a few days to get used to my strength, endurance and intelligence. This pretty much turned me into a super soldier. I run through doors, walls and other stuff. Ive cleared out planets on my own. You feel no pain and emotions come back over the course of about 2 years. Most newbies are very cocky with there new strength and I normally have to shut them up.
