I was wondering if anyone had any experience or advice with sleep problems after long rides? If I got out on a 4+ hour epic ride with a lot of climbing (4000 ft+), all singletrack, superfun, etc... I have major difficulty sleeping that night, I'm usually REALLY tired but I feel so exhausted that I can't settle down (if that makes any sense at all?) and I toss & turn all night. If I do a 2 hour fun ride (typicall weekday ride) I sleep fine. If I work out with freeweights at the gym for 1-2hours I always sleep really well. I'm guessing it has something to do with being aerobic for such a long time but I'm not sure what I can do about it. I have at times taken some over-the-counter sleep aids to counter the problem but I'd rather not take route if possible. Anybody out there have any suggestions?
