Prism vs eye patch for double vision

I have just had a prsim fitted this afternoon and OMG it is awful - my vision is blurred on that side and there is a permanent reflection or glare on that lens of my specs. The floor is distorted as well - not good as I regularly struggle to walk and have stumbled a lot. HAs anyone had this problem - does it get any better? I was told to persevere but not feeling like I can right now. rateful for any views. The consultant told me I could try an eye patch if this is not tolerable and that this would be fine for driving though a prism would be better if I could persevere.
