I have been through lots of choke with some older rescue horses from New Holland and just recently with a horse I just purchased this year. This is what my veterinarian suggested. After choke, Banamine for a few days, no dry hay or grain for 5 days. This means soaking both. For the hay I just use a muck tub and fill with hay then water and let it soak. Then I rinse and re-wet. I also was told that hay stretcher/extender is for some reason common with choke. My Vet. told me that it might help if I put my horse on an extruded food I believe it softens in the esophagus quicker than most grains. Once there has been choke there is a chance of scar tissue in that area which may cause additional choke incidents. Hope this helps.
