I don't notice my tinnitus when I'm busy. I have already attained what you say I haven't. You really are crazy man.
There is hope for you then. Now, try to engage in positive things when you are not working instead of moaning and groaning on why a cure cannot be found for tinnitus. If you do this, I assure you in time your tinnitus will reduce. Believe, me it is negative thinking and associating with your other negative thinking friends on MPP that keeps your perception of tinnitus at the forefront of your mind. You have said it yourself: when at work I don't notice the tinnitus. There you are, it is the negative company that you are associating with that is reinforcing your perception of the tinnitus. I told you tinnitus is 90% mental.
