Tori and Fit thanks for the good thoughts on my big day
Kumochi the dive will take about 6 hours. The actual swim out and drop to depth will take maybe twenty minutes the rest is all decompression stops as we work our way back to the surface. Nothing you can do to prepare for the pressure except drills to deal with emergencies.
Crazigerl there's a lot of "experts" out there when it comes to health issues,lol. FWIW I am an RN. Your BP is very healthy. If you were having ,lightheadedness or dizziness from being at the bottom end of normal that would be another issue. But if not enjoy the good numbers
Gotta run,
