I've been trying to find this for ages! To no avail. I really struggle with my hexb, I tend to find if I have it then I gain or STS.
I tried tricking myself into having it by having the scan bran coffee cake.. 5 scan bran used.. 5 scan bran hexb per day. That meant I could eat a whole cake a day and be 100% on plan!!
Did it work?
No.
:cry:
