I think it has the opposite effect … you have to work harder to breathe. The easier it is to breathe, and the more you are able to relax, the longer your air will last.

Guam is great. Lots of easy sites to get to...especially with a military ID. Most of the best shore dive sites are on the Navy Base and have great outdoor showers and dive access stairs.I've never dived Guam and don't know the sites.
Kudos for making it back alive and sharing your experience.
Equipment issues aside, did you check tide timetables and assess when the best time to dive is on that day?
Get a your whole reg set examined, tested, stripped down and adjusted. Have the tech explain the test results and show the results to you. Have them show you all the controls and what they do.
For sure your regs are not working as expected. It should not be possible to over breath a working regulator fully pressurized.
Congratulations on following your training to resolve to difficult situation. Thank you for sharing!
