Thanks for your feedback Paul
It's interesting to read about
the things that helped with your esophagus and stomach pain.
The insomnia is definitely a side effect of the Zantac, as normally I don't have much trouble sleeping, apart from when my stomach is bad when I'm usually awakened around 4 or 5am with nausea.
I've tried sticking with it for 3 or 4 nights in a row, hoping I'd get used to it, but end up completely exhausted and wired which only makes my stomach worse. It would be interesting to hear from anyone who has experienced this SE and has managed to overcome it.
Many thanks again for replying.
