I have recently, quite by accident taken my horse off of grow and win. He had been on it for about 6 months. He is an eventer in training, so he works hard. I did however noticed that he was cranky, frazzled, and alot spookier than ever before. I had almost lost hope that he would ever be a confident eventer again. Since being off the G&W he has returned to his normal confident easygoing self. What a lucky accident.
