raynaud's syndrome
"I've had no numbness in my fingers or toes since starting this medicine. Before starting I could not even carry a jug of milk without my fingers losing color from lack of blood flow. Even driving with mittens on was a problem. Now circulation is great. Only complaint is the terrible headaches and tiredness and a bit of insomnia. Still trying to decide what's worse....the headaches or the numbness all winter. "
