Mad cat,

Welcome to NeuroTalk. Sorry to hear of your injury and struggles with WC. We have seen this same WC struggle many times before.

Propranolol is not a blood thinner. It is a non-selective beta-blocker. Propranolol works to inhibit the actions of norepinephrine, a neurotransmitter that enhances memory consolidation.

It is used to reduce blood pressure, anxiety, and tremors.
It can have a negative side-effect on the central nervous system: light-headedness, mental depression, insomnia , vivid dreams, disorientation, memory loss.

I think you may want to try going back to the old dosage. It sounds like you did better at the lower dose.

I am confused at to what your current symptoms are. Please tell us all your symptoms so we can offer better support.

You should read the Vitamins sticky thread at the top. Getting good brain nutrition will be a help. Have you had any diagnostics or therapy for your upper neck ? Your impact sounds like it may have damaged the C-1 to base of your skull. This can cause a myriad of symptoms and make concussion symptoms worse. The first way to treat this is icing and being careful about neck posture.

More later when we hear more about your current symptoms. I doubt the placebo effect did anything for you. Propranolol can be a beneficial drug.

My best to you.
