The first makes no sense at all. Perhaps you mean 'I've had it up to here'! in which case it expresses anger with a person of situation.
The second is a little old fashioned but if you replace 'occasion' with 'reason' the meaning will be clearer.
The context for the third is probably as follows:
a) He cured a dog that was ill.
b) People heard about what he had done
c) The people believed that he must be able to cure people too and so expected him to do so.
