Well, make sure first that you address your tiredness and stress. If there are factors in your life that need attention to diagnose, troubleshoot and repair, PE becomes a LUXURY in those circumstances. If you are dealing with problems that require your attention to create a plan of attack and resolve them, it would be completely irresponsible to sit in a couch pulling your dick. There are priorities for everything in life.
Now if you have confronted and addressed all those situations and you are just in the process of taking care of them and happen to have extra free time for this, perfect. But do not distract from real life just for an obsession.
