Thanks for the feedback. Regulator is going in for cleaning this week anyway so I'll have them check it over in detail. I did notice it was a bit hard to pull a breath in and it sounded a bit nosier then usual.just a thought on the abdominal pain. check the second stage of your regulator, examine the mouth piece carefully for any cracks or tears. also check the exhaust valve and diaphragm. it is possible there is a small tear and it is admitting seawater vapor on inhalation. i had that happen some years ago. the abdominal pain is exquisite !
