I just got back from a weekend hike and I have noticed getting comfortable and falling asleep is definitely a problem. I have a comfy marmot down sleeping bag, a thermarest neoair trekker sleeping pad, and an exped inflatable pillow so I feel that I have a pretty comfortable setup while still relatively light-weight. However, I just can't seem to get comfortable falling asleep.
I started my hike on Saturday after only sleeping about 2 hours the night before. We hiked about 5 or 6 hours and the last part was very difficult, scrambling up a steep boulder covered incline. Needless to say when it was finally bed time I was exhausted. Still, I was up for at least an hour or two before falling asleep and woke up several times during the night and couldn't fall back asleep.
I think the problem is that I am a side sleeper and sleep with a large body type pillow at home. I just can't fall asleep lying flat on my back. I am a pretty sound sleeper so noises and such don't keep me up, I think it is primarily just a comfort issue. My last time out I had similar issues. Anybody else a side sleeper or a pillow hugger and have problems getting sleep on the trail? I am worried that for long distance hiking lack of sleep is going to be a problem eventually. I would like to think that I would be so exhausted that I could fall asleep standing on my head, but this weekend gives me doubts.
