Reglan and lunch

I am a 66 year old female, and now taking Citalopram 20mg, and Requip. I was prescribed Metoclopramide Tab 10mg. for acid reflux. I was to take them four times a day, 30 minutes before eating, and at bedtime. I took the first pill at lunch. Shortly after, I became very weak and nauseated. I went to bed. I was able only to get back and forth to the bathroom. I skipped the dinner pill, and felt a little better. But I took the bedtime pill, and became weak, nauseated, and had arm and hand tremors. The next day, I took one more pill, with the same effects. My son found on the computer, the side effects were similar as mind, and was worse with seniors. No more pills did I take. It took 6-8 hours to get back close to normal. That was yesterday. I still feel a bit panicky at times, fearing it is happening all over again.

My husband had taken Reglan years ago, with no bad side effects...
I never want to try it again...
