Travelling with controlled substances through Doha, Qatar on a connecting flight?

I just need to fly from Thailand to America and am considering using Qatar Airways. I know the word controlled substance sounds like a bad word so let me just explain in more detail. I have some sleep medicine, just about 4 pills of Lunasta with the prescription on a bottle that is my brother's (same last name). I also bought some Valium (about 4-6 pills) in Thailand that is in it's original packaging, no prescription. These pill woulds be on me, not in checked luggage.

I fly coach only and I plan on using this sleeping medicine to make the 26 hour journey not a sleepless one. I've got a bag of medicine I travel with that has other stuff in it too that would be in checked luggage. Stuff that is not a scheduled control substance but does require a prescription in some countries like ibuprofen and pseudoephedrine. And a lot of allergy medicines. Some with my name on them as a prescription and others not.

My wife suffers from migraines and since we are in Thailand I would like her to go ahead and get a prescription for pain medicines (narcotics) for that in case she has an episode in America. It would be a prescription for about a week's worth of medicine.

Questions/concerns: Will my stuff be confiscated? Will I go to jail? I've heard of the story where there was a young man who had some trace amount of weed in his shoe lace and was put into jail... My alternative is to fly through Japan but it costs about 300-400 dollars more that way for 2 people..

edit: and when I say narcotics, I mean clinical narcotics, like vicoden and tramadol. Not like street drugs... that word has some different interpretation.
