Very brief breaks mind you. Also what matters is your mindset when you do resume play. Make sure to save replays when you can if you did lose. If you can look at a match without all the frustration in your mind it's very easy to see where you went wrong.
If you lost to spamming sledge (assuming lag isn't an issue) then it's because you were trying the same things in similar situations and failing. A common mistake is to misjudge distances trying to punish sledge follow-up.
