... back. I've been taking it for over a year, and it started out rocky with side effects but those got better and became tolerable, however recently I've been having bad acid reflux pain after I take it. Has anyone else had that problem? And I know you aren't supposed to take antacids containing magnesium or aluminum within 2 hours before or after taking neurontin, but I'm not sure, does that include Zantac? I haven't been able to find much info on that drug interaction
