Yes, you can do them yourself, easy. Its like one stab but then comes blessed relief so its worth it. The muscle in your upper arm or thigh. The relief comes like a head rush at first but then subsides, a bit faster than what the pills do. Does sublingual zofran work on your nausea?
Typically, I can manage them fairly well and I can often go weeks with barely needing an Excederin but then I will get on a roll of a week, two --where I need the RX stuff (and I only take 1/3 pills at a time).
