I don't have propranolol and hopefully that won't impede the process.
What we have to remember is that Stan was likely not an expert on everything SN related. What we know about him is what we read about him. We can only assume that he researched this topic carefully and came up with a way that he believed was the "best" way. As we understand, he had CTB in a manner which was effective for him. We shouldn't take what he supposedly used to CTB and then superimpose that onto ourselves. (Unless you want to). We all would like to believe that if a certain individual CTB successfully using a particular method, then we should follow suit. However, we are all different from one another in many respects. Some of these are simple such as differences in weight, metabolism, medications we take, health status, etc. So, the point I'm trying to make is that we just need to choose what we would like to do or use in light of these ever-changing reports. I may choose to skip the antacids or blockers but someone else may not.
I think it just comes down to sharing info with the community and then each person can decide what is best for him or herself. It's frustrating at times... Or even most of the time, but we still must make a choice.
