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.
