I have tried beta blockers and they really just get rid of the thumping heart sensation but you're still sweating and terrified. I have had some good success with taking full B complex and D vitamins before speaking though.

I've had success with Valerian, it is a quite mild sedative and anti-anxiety root. It's just enough to get over the pre-presentation anxiety and get in to the flow.

Yes, if you have mental problems with public speaking, then beta blockers will not help you. They only mitigate the physical symptoms of stage fright.
