I hate to see a grown man torture himself. I truly do. You sure this four-day thing is a good idea? It's like a guy who finally runs a marathon then decides the next day he's gonna run two. It's not healthy, I tell you.Hey! My goal was 3 days, after a couple attempts I finally made it 3 days!! If I buy something today, I will try to go 4 days the next time!! (baby steps). Good luck with your fur baby!! <3
