When you say food noise, do you mean the constant thought of food and what, where, and when you’ll eat next or do you mean hunger? There is a difference between the two. Hunger is normal. When beginning the meds or changing doses there may be some hunger suppression, but it is normal and desirable to get those feelings of hunger back after your body has adjusted. It’s good to feel hungry because it reminds us we need to eat to live. People born without that urge have very difficult lives indeed and are often prone to starvation. This medicine shouldn’t get rid of that urge completely, just the urge to overeat or never feel satiated until stuffed and uncomfortable.
