I personally don't feel that I've struggled with monads that much. Perhaps that was because I was okay with "I know how to use monads or wrestle them into getting something to work" (took 20 minutes) until I got to "I understand what monads are for, I understand how to compose them, and I can see how they aren't a hindrance and in many cases are useful." (has taken 4-5 months on/off learning). I haven't ran into memory issues yet, but I have heard others have a very hard time reasoning about memory/space leaks. However, something I hear less often is that the memory problems people have also happen in other languages.
