​I underwent a type of eye surgery called a trabeculectomy last year, and I wonder whether this has any implications for scuba diving.

​I've occasionally had problems clearing my ears, particularly my right ear, and I take medication for allergies and nasal congestion. A couple of months ago I got a sinus infection, and in the weeks that followed I saw my regular doctor once and an ear, nose and throat (ENT) specialist twice for congestion and muffled hearing. The doctors noted fluid behind both eardrums at each visit and prescribed three separate courses of oral steroids and antibiotics. I'm going back to the ENT in a few days, and I think I may still have fluid in my right ear (I can feel air moving when I yawn). He said he would want to insert tubes if the condition hadn't resolved. I am concerned about the amount of time this procedure would keep me out of the water and about the potential for scarring of my eardrums. Do you know of any other options besides ear tubes for draining the fluid?

Recently my doctor took me off warfarin and prescribed a newer anticoagulant, dabigatran. Are there any concerns regarding scuba diving while taking this medication?

​If 1.5 gallons of water is considered too much to drink (From the Medical Line, Fall 2014), what is your recommendation? Would it not depend on the environment and activity? When I worked as a river guide rowing the Grand Canyon, we would easily drink more than a gallon of water during the day.

​My next dive trip is taking me across the world. Whenever I cross time zones, I suffer relatively severe jet lag, which affects my ability to dive safely. What might I do to minimize the effects of jet lag?
