mance anxiety
"I had two very different experiences with Propranolol. 

After a long break from work after having a baby, I needed Propranolol to start all the interview process, etc.

After taking it everyday  (40mg twice a day), I  developed a terrible Insomnia. 

Then I found myself in a nightmare taking something to calm me down in day time and not having any sleep AT ALL at night because of it. So I was prescribed sleeping pills. I managed to stop it all after a few months and took nothing for years. 

I started feeling a bit anxious once again and started Propranolol couple of weeks ago. 

I realised that if you take it small doses, only when needed, it's actually fine. Just before speeches, interviews, 10mg up to 20 mg. No Insomnia! Good luck"
