Another suggestion is just say you will read at least 2 pages a day. You’ll probably read more but a couple of pages every night will get you back in the habit soon enough

If you are trying to get out of a slump I’d suggest going for your comfort genre. Some great books suggested here but some I’d find a bit hard to keep going with to start. For me it would be something like Strange Sally Diamond, Demon Copperhead, Hamnet, Babel. Historical fiction like The Rose Code
