I just got certified this past weekend in Palm Beach Florida. I had a lot of trouble with equalizing my ears during the dives. None of the dives were deeper than 20 feet. During the last dive, I tried some vented ear plugs, but they did not seem to help much. After the dives, I continued to have trouble with my ears feeling congested and clogged. Any suggestions on what I can do about my ears during dives? I am afraid that I won't be able to go very deep if I had this much trouble at only 20 feet.
