I have nitroquik - sublingual
nitroglycerin - to take if I have angina pains - this morning about 5 am I was miserable and couldn't tell if it was heart or ms symptoms and I took one. As always it stopped my discomfort, depressed my already low blood pressure and I went to sleep for about 3 hours. I've used nitroquik for the past 3 months or so and it always stops the pain and gives me relief within minutes.
