If I find out what my secret is I'll be sure to share it with u lol. I aim for at least 4ltrs still / sparkling water addition to amount in my packs, I space the 4 packs throughout the day, never double up a pack or eat within 3hrs of each other, 1 can of coke zero per day, 200g specified veg. Other than that I have no idea but its working so I'll continue with this lol
