Do I have to wait 2 weeks so that my desensitized get cured?

I am NO DR. but, why is it desensitized? [ Like I have not gone through it ] I have for a month & not 'C' . Sometimes 2x's a day. Others I hope for 1 time a month.You made sense to me! I'm in my down slope right now. '?' maybe it is watching a movie too many times. It get boring. Just a thought.( not )
