I checked again today the throat tickle starts aroung four hours fifteen minutes .
After taking mestinon recovery starts in about 20 minutes and is fully recovered within an hour .
Because I was not sleeping in hospital at night I rarely got even with a sleeping tablet more than four hours sleep.
Now feeling I cannot afford to be asleep now more than four hours .
I am going to GP open surgery first thing in the morning.
At four hours fifteen today while I was doing my one task for the day in local store at the cafe tickle started and I could not speak properly to the assistant .recovery as above .
