I even did try bread and rice as well but didn't work.
By the way, after i post my problem that day, the next day i didn't feel anything stuck in my throat again, but i woke up with hurt in bottom throat and my right chest, not heart i guess, it's like somewhere near lungs. I was started to more worry, and keep trying finding the information what's wrong. And i got this link http://www.mypacs.net/cases/DOXYCYCLINE-INDUCED-ESOPHAGITIS-173438.html. That antibiotic was doxycycline for my skin for bites.
The page cleared me about what happened to me. So it's not the tablet stuck anywhere again, but the hurt was becoz of my esophagus' tissue was damage. I just took Mylanta and didn't help much.
The next day, Monday, i met a doctor and he gave me 2 tablets to drink for 2 days, and he said time will recover the tissue back. Today i feel alot better even still can feel some hurt. But just give it some time and i eat more yoghurt, i hope i can be back to normal.
Try drinking some very warm water, as you drink it, stand on your tip-toes and then drop down hard as you swallow, this might jar the pill loose. I use this procedure for my hiatal hernia at times, it works.
I think you are right and you didnt take enough water with it, how about you try a piece of bread or something that has more substance than banana, keep swallowing liquids ....if it continues get it checked out ,it will probably solve itself
