I'm also in my early 50's and tryed OPing yesterday for the first time with Flaxseed oil (only thing we happened to have on hand). I also had a terrific sense of mental clarity, unusual sense of patients with things, etc. My blood pressure was also high 150/95. Immediately afterwards it dropped to 120/88 and stayed that way for the next few hours.
I woke up today also feeling better rested and not as groggy. My results impressed me so much that I did it again this morning after waking up. As other people report, even after my first pull it was amazing how solid my teeth felt - no looseness at all. This is cool - I'm sure I'll be doing alot of this from here on.
