I became light headed about 20 minutes into class and couldnt do both sets of poses from eagle thru three although it did improve a little on the floor series. I had only been on the beta blocker three days and then stopped because I didn’t like not being able to do yoga. However my BP is just so high now that I must now take these. My doctor thinks that after my body adjusts I should be able to handle bikram. Have you heard of many people on beta blockers who take bikram?
