Caffeine for us post-ops 6 months and under?

My surgeon OKed one 8oz coffee per day.  Im 10 days out.  It helps with BM's. Sorry if TMI but I was having serious constipation issues.  Right now I only have 4oz in the morning mixed with a protein shake....helps IMMENSELY .  3 grandes a day is 3 shots of espresso.  I dont think thats very much.   

One more thing lol.   I switched a few weeks before surgery to a grande iced coffee w/ two pumps SF vanilla.  No milk.  It took a few days to get used to the taste...but now I really like it.  You could also get a shot of espresso with water (cant think of the name of the drink right now)  if you like the espresso taste over the drip coffee.   I think taking out the milk and limiting the syurp pumps will give you a very low cal drink.  And....its cheaper than the latte.

ps: I dont know what it is about Starbucks....the taste of their coffee is addicting in it self.
