There are thing you can do to make naps more effective. I do well with a 20 minute nap in mid-day, but I'll feel groggy if I nap for too long. It's better if I don't lie down, but instead sit in a comfy chair, so I don't go too deeply asleep. If you drink coffee, have a cup before the nap, and the caffeine should kick in about the time you want to wake up. Other suggestions can be found on line.
For me I think part of the problem is that I cant just go to sleep it takes me almost 30 minutes just to relax into a state where my mind isnt thinking.
