You are hearing the phrase quite correctly, it’s ddylen i ddim. As you suspect it isn’t related to “dilyn”, but exactly where it comes from, I can’t really tell you that - I don’t know any “base” word.

What’s happening here is that you move the “I shouldn’t” part into a sub-clause, and the wore introducing that negative subclause is na:
She told me that I shouldn’t drink too much - Ddwedodd hi wrtha fi na ddylen i yfed gormod.
Note that the ddim usually disappears, but you can leave it in.
