The dose and timing of Reglan makes a lot of difference. I was on it 4 times a day for 6 months and got facial twitches which took 2 months to go away. For some people they are permanent. They can be violent and permanent even with 1 dose, usually the IV stuff during surgery.
I think I could probably take an occasional Reglan to speed things up. I'd never go on it as a regular treatment again though.
