I think it works for some people and not for others!
We found that adding a dream feed just meant that DS woke at 10ish as well as his normal night feeds around 1am and 4am. It took a little while to fade out that waking again, too. He was doing a long stretch from 7pm to 1am beforehand so I wasn't pleased!
Cluster feeding is also an option. I fed 3 hourly in the morning and closer in the afternoon - something like 7,10,1,3,5,7.
