Just deflate it a bit and you'll be fine. I put my self-inflating in the hammock fully inflated and just deflate it to a comfortable point when I first lay down. In the summer I just leave the valve completely open. In cooler weather you'll want to be sure to leave some air for insulation.
"Mother Gue", I says "the Rocky Mountains is the marrow of the world," and by God, I was right. Keep your nose in the wind and your eye along the skyline.
