I also love physical books but at certain point I had to choose between getting used to ebooks or not reading at all since physical books are expensive and I had no possibility to get books from local library.

For ebooks, you may need time to get used to them. I struggled as well at first but then I found the book that completely sucked me in, to the extent that I did not care about the discomfort anymore. After that, reading ebooks came gradually easier and easier. By now I have read ebooks for about 10 years, most of it on the phone or tablet (thankfully, I have Kindle now).

What can also help is trying different setups (fonts, backgrounds, etc.)

Great thing about ebooks is that there are free ebooks and eLibraries + if you have Amazon, they have monthly offers for really cheap.

As for audiobooks, I have tried them but I get easily distracted, so they are no no for me.
