Reflexivo Pronouns

Question

When would you put the reflexive pronoun at the end of the verb? I know two of the exceptions are for present progressive infinities, informal future, and what's the third? w/ an example.

Answer 1

with two verbs back to back or "dos verbos juntos." i.e. "me gusta acostarme temprano." "acostarse" is to lay down as in going to sleep at night.
