Using Draw for ulcers has been around for years, but curious what your protocal was after the treatment cycle? They say at the clinic to use only if showing symptoms...well I would like to prevent ulcers from even forming...not wait for ulcer signs. 

If your sure your horse doesn't have ulcers " if not sure  I"d get your horse scoped" Succed is wonderful. I have my mare on it and my vet uses it to on her barrel horse. My mare was scoped and had ulcers so she had the 28 day gastreguard and then went on succed. JMHO I wouldnt put her on anything if I wasn't sure she had ulcers. 

Doc Mitchell told me to give 1oz every other day.  If a competition day fell on an "off" day give 1oz that day as well.

This was obviously years ago.
