OP, so sorry you are going through this.
It may be too late in your cycle, but have you talked to your RE about changing protocols? I always get antagonist/agonist confused so I'm not sure what the protocol I used is called, but after a couple days of absolutely horrible side effects with Lupron (incl. one my RE hadn't heard of before), he switched me to a protocol where I took Cetrotide late in the cycle to suppress ovulation.
Lupron is truly evil, and RE's give you basically no heads up for how horrible, life altering (even if temporarily) it can be.
If switching isn't possible, hang in there! You are not alone...
