That sucks brother, waking up tired is the worse. Not to mention that you are having 2 drink 2 cups of coffee to mask the symptoms of the unrest. Coffee is great but not mask the underlying issue. Definitely go get it looked at. Who knows it may be something super simple to solve. No sense in dealing with sub par rest. Life is short, you should feel amazing every morning after a good nights sleep. It is very important for quality of life and everything you do.
