I'd like to thank u'all for your help and suggestions. Unfortunately I still haven't completed my first pool session, but I was finally able to get over that gag problem. A got myself a regulator and replaced the mouthpiece with the small soft bite kind, and that seemed to do the trick. I dived in the pool today til I ran out of air,it was awesome! I'm now able to clear a partially flooded mask, something I spent all day yesterday trying to get right. What I'm currently working on now is breathing underwater with no mask. For some odd reason I keep getting water up my nose. Ouch, any tips?
