Any of you have problems with this? It usually happens to me when I have a lot on my mind. It's a bitch. Thoughts/remedies? 
Try to avoid screen time (TVs, computers, etc.) for at least an hour before you try to go to sleep. Don't work out within about 2-3 hours of going to bed. Don't eat meals or drink any caffeine within 3-4 hours of bedtime. Reading a book can help divert your attention and make you drowsy. Taking a hot shower can raise your body temp, and the subsequent drop in body temperature will make you drowsy. Doing breathing exercises can also lower stress levels, which should help you keep your mind from fixating on the worries of the day (

Melatonin in low doses can be effective (large doses can leave you feeling pretty mumped up in the morning), but there aren't really any reliable studies on whether there are long term side affects or not. Get a white noise machine, it really helps. Also, use your bedroom only for rough ridin' and sleeping if at all possible, our bodies tend to subconsciously associate some of our more frequent hangouts with certain activities. The fewer activities you do in your room, the more likely it is that your body will associate your room with sleep. I try and do all of these things on a regular basis, and I don't ever seem to have a problem with a wandering mind keeping me up anymore.
