Signed a non compete clause in NV. 7 mo. later salary and comm cut over 33%, is the non-compete enforceable?

The position is in sales and I have the opportunity to move over to a competitor and make 4x as much money. They sell the same type of services. Can my current employer enforce the non-compete clause if they changed the terms of the contract by lowering my income so dramatically (he did this to the entire sales staff, I was not singled out for poor performances)? Would a judge uphold the contract if I I would be able to support my family again? To say the least, this has been financially devistating to me! I just want to ensure that I am not jumping from the frying pan into the fire but breaking this clause! Any guidance would be appreciated! Just as an FYI, the only reason I stayed with the current employer after the salary was cut so deeply was that I needed my health insurance desperately. This is a small company and they do not participate with Cobra Insurance. I felt trapped, but the insurance was just too important!
