"Forced to take more endone than I wanted to - got sick as a result"

I had surgery on my hand. Afterwards my nurse asked me how much endone I wanted - 1 or 2 tablets. I said I didn’t know as I’d never had it. They told me to take two and then went to get it.

While they were gone, my partner and two other patients in my room informed me that since I hadn’t tried it before I should only take 1 tablet at first. 

When the nurse returned, they were with a senior nurse. I told them I was only comfortable taking 1 tablet. They insisted that I had to take 2 as it would be, I believe, too much paperwork to change the dose. I still said no and so did my partner. The senior nurse said I didn’t have a choice and that they knew best. I said no again. They, I felt, shoved it in front of me and again said I didn’t have a choice. 

I took both tablets but didn’t take the additional 2 panadol tablets. 

I was then very nauseous and couldn’t eat or drink for hours. My next nurse then told me it was unusual to give 2 tablets to someone who had never had it before. I believe the other patient in the room said they also saw them force me to take it.

I think this is terrible service in an otherwise good experience.
