Do try to stick with it! My first week was really awful. I felt as if I had flu, the withdrawal was so bad. It passes really quickly, and then you will be flying too, honest!
As for the milk in your drinks, I really really really missed that too. However, just once in week 8 , I gave myself a splash of milk in my coffee....oooh I was looking fwd to that!! But, it just didnt taste as good as I remembered, so that was quite a big step for me. Now I drink the occasional coffee , whereas once I dranks 6-8 cups or more a day. I rarely drink tea, again an occasional Earl Grey, but I do like Clipper's Peppermint Green Teas; is really refreshing and totally fine on LL.
I hope you keep on going well, and do keep posting coz it really helps!
