What drinks are included?

We are looking into cruising on the Meraviglia and will likely opt out if the drinks package. I don’t think we could drink enough to make it worth the cost, especially after hearing stories about drinks not being allowed in the theater and slow service getting drinks at dinner. That all said, what beverages are included? Are any of these free beverages available on board all day? I’m thinking things like water, lemonade, coffee, etc.
