Metoclopramide is an Anti-sickness drug. They usually give it to people having chemo. I was addicted to (although I had to get my Dr to prescribe it) I would panic if I didn't have any in the house. It wasn't a physical addiction but a psychological one.
Eventually my mum pointed out the fact that I was still panicking everyday while taking them so they weren't doing much good. So I slowly started to stop taking them. When it was time for a pill i would wait as long as i could without taking it, till eventually I could go days without one and then weeks. I also found that after a few weeks not on them if i took one, the side effects of restlessness etc were Sooooo bad so it put me off taking them. I still have some pills in the house, they go with me on long journies. But I havent taken one in a year or so now.
The other problem is if you take a drug too much it becomes ineffective and cancause problems with your Liver.
Be courageous, believe in yourself, and be the best woman you can be. I'm with you all the way.
