Well for me I look at congestion in lungs and sinuses. If there is none and I can plug and clear my ears that I am good to go. Musinex and any antihistamine will work good but cant be depended on. If you are done with a cold and just want to help fight and residual clogging then OTC med would work.
The way I look at it if I "THINK" I need any antihistamine to do a safe deep dive I wont do it. Stick to the shallows a 20 ft reef and there wont be much of a prob anyway. As you know a reverse block is not a good deal and not worth it
Safest bet if you second guess it pass.
