Oh, what I wouldn't give for a good night's sleep.
In my opinion what brings the good night's sleep the fastest is dropping the rope. And meaning it. What also helps is to not sink to mean or rude behavior, regardless of how anyone else acts. Your friends will wonder about that with you, but trust me if you do something you'll regret later you'll push that good night's sleep out further and further.
The missing comes and goes. Have you tried re-doing your behavior patterns? It helps.
