<<Disclaimer: Verify this information before applying it to your situation.>> Thanks again to everyone who responded to me! You are wonderful! Suggestions for a heavy duty pain killer: Percodan, Ultram, Darvocet (NOT generic) (2 people), Fiorinal (not generic), Anaprox, Lortab Elixer, Lorban. Two people mentioned using Vicoden without problems and one reported no problems with Tylenol/codeine. I will call to confirm the current status of these with the manufacturers before taking them- Thanks for all the suggestions. I won't summarize the responses about general Nepal travel or weight loss, as it was a pretty specific question. If anyone wants to hear more, let me know! But thanks for all the response- I'm nervous but feel preety good about this trip and am very excited! -Becca Buffum
