i saw this and just had to comment, when I was using D, I would go out and surf on the smaller days. For the days when it was head high and over I wouldn't go out because I could barely breathe at all since I as a heroin user I knew I would be unable to actualy survive the beatings of OH (overhead) high jersey death barrels.
anyway to the main point yes there were times that I had surfed for a couple hours (a very exhausting activity) plus you have to keep in mind it was winter and in winter you have to wear the thickest wetsuit available (think surfing with like 7 pounds of rubber). So Id come out after my session, take off my suit and go get ready to do a big shot...
the shots I would do after a surf were absolutely incredible. So powerful. Because I would be so fucking tired and my body felt like it had gone through a tough workout then I do the shot and after the rush, I was no longer tired, had energy all of a sudden, and the body obviously did not hurt had no soreness whatsoever.
So yea doing a huge shot after exerscice is awesome. But only do this if you have a tolerance of course.
