Hi All just thought I'd check in. 6 weeks post surgery tomoro and I'm down 17kg which I'm pretty happy about. I'm taking all vitamins biotin hair skin n nail s but I've had alot of hair loss patches in fact pretty depressing. I've had to get top hair piece to cover patches. It works well but I hate wearing it. I have noticed stubble growing back so I hope it's not permanent. My bowel is also incredibly upset grumbling really loud and runs. I come over all sweaty and need to run to toilet. I thought it was dairy so I take a lactose tablet after eating it but now I'm not sure. Any suggestions
