You are doing so well Fur 19lbs is amazing!! You will be fine on your weekend off when i went away i had breakfast at hotel tried to stay away from carbs though , had shake for lunch then a proper dinner and a couple of cheeky malibus omg i can smell the coconut yum!!!!!! I still managed to lose 1lbs that week as long as you don't have huge binge and get straight back on plan after the weekend and remember keep up with the water you will be fine. Most importantly don't feel guilty see it as a reward for doing so well and even if you do gain just a week back on plan and it will be gone!!! xx
