Do you mean sucking wind or chewing wood? My gelding was a very bad wood chewer in his stall. What fixed it 100% for him was to staple a tarp over and around all of the wood surfaces in his stall. It is kind of ugly, but it keeps the wood safe. You can find less hideous color tarps than blue :)
Some people put logs in the paddocks to give them something they are allowed to chew on.
Increasing exercise might help, but my gelding was worked a lot daily in different environments and disciplines, and still liked to chew. Some horses do it out of boredom though. Maybe throw a jolly ball or other horsey type toy in with her. Of course if you are talking actual stall, not stall/paddock, these options are somewhat limited. I have seen people secure rope for horses to play with in their mouths (up above their heads) - that might work in a stall, but I would be really careful about something like that because it seems like a potential hazzard in many ways.
My best fix is definitely the tarp :) They don't like to chew on the texture.
If you are talking about sucking wind - I think that is a very addictive habit started through boredom or stress, and I have little advice for that one :)
