thanks guys. and thanks for the link to the other thread. i had a bit of a look online too and found that some places said that inderal DID cross the BBB (blood brain barrier) while others said that it didn't. my psychiatarist SWEARS that it doesn't... i don't know what to think.

i get performance anxiety when i go to ask questions in seminars when profs are there. i raise my hand (and get put in the queue) and then my heart starts beating really fast and loud and my hands start shaking and i start sweating profusely. i try and breathe... and tell myself 'it'll be okay people are friendly and accepting, it'll be okay' but that doesn't have any effect on reducing the fight / flight physiological symptoms. i can't focus on the discussion while i'm waiting in the queue and i start to have this terror that i'll be incoherant and / or faint or something like that. i'm perfectly fine when the profs aren't around, however.

psychiatrist said that i should take it once and see how tired i get. then try and take it and ask a question and see how that works out. if i can find a dose that doesn't sedate me too much then my body should habituate after a few times of successfully asking questions. he swore that it wouldn't cross the BBB and / or affect my thinking. i guess... i should try it and see, huh...
