I was mini-sup for a while and a lot of DNIF IPs were SUPing. One of them had slipped disk with recovery over 3 months. How long did it take you?
It was 3 months leading up to surgery, and exactly 3 months post-surgery because that's what the flight doc told me was the absolute minimum. I probably rushed it going back to flying but I had some personal and professional reasons that drove my decisions.
Hopefully I can adapt well to Gs.
Most people do, if they really care to. Hitting the gym and doing the recommended weight training helps, but you also have to be in good aerobic shape too. Lots of muscle mass and low fat can help with absolute G tolerance (how high you can go), but sustained Gs absolutely suck if you're not in good aerobic condition too. You just need to find a balance and your body will adapt... or it won't. But usually if you make any effort at all to prepare for the conditioning you need, you shouldn't have any problem.
