I have been prescribed Reglan but I have not taken it due to the side effects that it can cause.
I have been on Domperidone and while it did work for several months, it eventually wore off and I stopped taking it.
I think Reglan is supposed to tighten your LES but like all medicines of this avenue it will only last for a while.
It's up to you to weigh up the pro's and cons of taking it, considering the risks.
Hope this helps,
