Two more things I wanted to add:
1. At the time I was dating my boyfriend (now my husband

) he was living in Germany and I was in NY. So lots of TATL flights, either via LHR or the ORD/DFW FRA flights. So know that I've gotten through some long ones.
2. I do still take Zoloft, 25 mg daily, for the anxiety. I'm open about this because prior to starting the Zoloft some 10 years ago, panic attacks were taking over my life. I was going from a fairly independent young woman to someone who was nearly homebound. The meds helped get the biological causes under control although there are still triggers that I have to work through.
Sorry if I've rambled on. I just wanted to add the above so that you have a better picture of my experiences and situation.
