[Grammar] prepositions

Can we use I have difficulty sleeping without a preposition and Difficulty in sleeping ( is it possible to use of instead of in)?
Can we use difficulty with anything? In other words, with what exactly can we have difficulty? For example, with money, with friends, with English?
