There is no shame in going to the doctor for medication. It is not a sign of weakness, but of wisdom. You would seek help for other physical issues. Many, many men here have took medication to help them during this terrible ordeal. You have to be able to sleep, eat, and think. You have to take care of yourself first.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
