Hiya Danii. Good on you for restarting, it's hard but well worth it. Exante say it's around a stone a month on total solution so you're looking at about 6 weeks. Maybe a bit longer as you're having 4 packs instead of the usual 3- I bet that after about a week or so on 4 packs your appetite will decrease and you'll only want 3 anyway. Sometimes I don't even want 3! But eat the third one anyway for my vits and minerals. Good luck!
