Yes - that "unmasking" of the pains the morphine has been covering up.

I tried to quit three times, but it was too much. Worst experiences of my life. Such hell.

Sorry to hear that you are going through that same thing, [yes, I still am].

I applaud you for going to work, it must be difficult. I kept working as long as I could, but eventually I just had to stop, or die or something... even my boss was saying it was obvious I had to stop, I was cramping up on the job, and my body language was giving away what I was trying to keep to myself.

I hope you can keep working - it does give a person a sense of being needed. Staying "as active as possible" helps up to the point it harms I guess.
