git - Recover uncommitted changes after a mistaken merge -

I was working in a branch (SRC) and there was a part of a countless transformation in that I was going to move to another branch. (

DEST). I was in SRC and did "GIT merge waste". First forgot to make my changes, it seems like work is lost on work day. Any help would be greatly appreciated. Any way to recover my changes?

You can only undo changes of the merge

  git Reset - merge
