Propranolol ROCKS. I know my shit. I'm actually good at interviews... except for the crippling adrenaline rush. It's deep down in my lizard brain and I cannot control it. I'm sure it kept my ancestors alive when they were running from sabre tooth tigers, but it's not much good today. Propranolol just switches off the adrenaline rush like a light switch. It's uncanny. And amazing. I tried everything, and this was the only thing which worked. I regret that it look me so long to find it.
Note: don't take it for every meeting. Save it for the big ones. Test in the range of 10-20mg. Takes about an hour for full effect. I find the effects can last 4-6 hours afterwards. I get two side effects: an upset stomach and I feel tired in the evening. I take an imodium to solve the former, and a good night's rest for the latter.
