I got 99 problems, but peeing ain't one -_-

Tonight we are flying to DC for a wedding.  Anyone who knows me knows I am deathly afraid of flying.  I've been agonizing over this flight for weeks!  My usual agony stems from anticipating turbulence, being cramped in a middle seat and the airline losing my luggage.  I can typically override those issues with 2 prescription Xanax and a glass of Pinot at the gate.  However; with my growing belly and having to push a stroller through the masses I'm pretty sure being drunk will not look good on me- not to mention Xanax is bad for the baby (I looked it up just to be sure).  My biggest concern tonight is my bladder!  If the flight is anything like my typical evening routine I've calculated I'll have to pee at least 6-8 times between arriving at the airport in Fort Lauderdale and deplaning in DC.  I'm not quite sure how this will all work since besides flying the only thing I probably hate worse is getting up on the plane and walking!  For some reason I feel like if I'm in my lil seat saying a quiet lil prayer the plane is more likely to stay in the air.  I know it's irrational to think my ??5 weight will bother the steadiness of the plane, but I have a true phobia people and no one ever said phobias are rational!  On top of my issues my son is not the best flyer.  We flew with him in January to a wedding and it was just miserable.  God bless his lil heart.  His ears were popping, he had just conquered saying 'hi' and 'bye' so everyone in the airport and on the plane got to hear him practice it over and over again.  I tried to be prepared with snacks, juice, toys, his paci, and a blanket, but nothing seemed to interest him except crying and talking to strangers.  I foresee this being quite a long and not so peaceful trip this evening.  Any suggestions for traveling with a toddler and a mommy who needs a diaper just as much as he does?  I'm all ears!
