Gastroparesis

Has anyone had a better experience with Reglan vs Domperidone? I know Domperidone is supposed to be the safer option, as it supposedly does not cross the BBB, but I just had a terrifying experience with it after being on it about a month. I took one and a massive rush of adrenaline went over my body. I was sweating and I swear my heart skipped a few beats. It's caused me to be jittery and panicky at times as well. I desperately need a medication for motility, so this is very disheartening that this happened. I just need some advice on where to go from here and know others experiences with both medications. I took Reglan for a short time, but was afraid of the effects from it as well, so switched, and here I am terrified of the domperidone also. HELP!
