Kennerly,To 49ers point regarding whether after 3 years enough is enough, I"m in a very similar boat as you both seem to be, so I can definitely "feel your pain." I think however that focusing on elapsed time is a faulty approach. Instead we should think more in terms of milestones reached, or checked off if you will:
You make some good points but what if you can't stay asleep on the machine as I have been unable to do no matter what so far? I am still not out of things to try, which includes a desperately needed full scale sleep study that I can't for some reason get sleep doctors to order that I have seen. I am trying another route next week that hopefully will work. But if that doesn't provide any answers and the general consensus is that my nasal issues aren't impacting pap therapy tolerance which I don't know is the case or not, it is time for me to move on.
I guess my point is you could spend years chasing milestones that may be simply unobtainable no matter what you do. It is clear to me that there is a significant subset of people even though many folks on this board would deny it who can't use cpap in spite of their best efforts. Whether the three of us are in that category, I have no idea but I think we need to be honest about this and stop pretending that everyone has a happily ever success story.
Glad I hoped you on the generic drug issues.
Anyway, let's hope we all find some answers.
