I start every week with a lot of motivation, planning everything and so on, but in the afternoon, a friend comes over suggesting we grab a coffee and I should order something, and my willpower just disappears. I don’t really have much weight to lose, but honestly, this lack of willpower takes a toll on me. I don’t understand why I’m so weak in this regard. Is it like this for you too, or am I just too relaxed? Give me some advice.
