Angina
"This drug has literally changed my life in a very short time. I was having horrible chest pains, with a mixture of general anxiety due to work/home stress. Cardiologist found source of my chest pain is a narrowed subclavian artery. 

The chest pain completely stopped within 24 hours. The only real side effect is difficulty sleeping if instructed to take it at night. I switched to taking it first thing in the morning and I now sleep like a baby. I give it a 9/10 solely for that side effect. I did feel very lethargic when I first took it, but that went away completely after 2 days or so once my body got used to the meds.

I feel much more calm than I did before so this medication has really changed the way I feel. improvement is noticeable"
