Propranolol
"Propranolol worked great for me until I was put on the 80mg slow release capsules. After 2 months of taking them I felt like a zombie every morning, and the effect would last all day until late evening. I thought I was going mad and was seen by the mental health team at the hospital who told me that propranolol can actually cause depression in some people!!! I gradually reduced the dose but now my anxiety symptoms have come back and I have insomnia."
