I've been on Rybelsus since January 2025 (and before that on the Ascend Plus trial until I was randomised into the placebo). For me, it definitely has an appetite suppressant factor, and it makes me feel full much sooner than I was before and I stop eating then. I also take Canigliflozin (Dapaglifozin's cousin). I haven't experienced headaches on Rybelsus, so can't comment on that. I've lost over 3 stone in weight. My only downside with it is that I experience lightheadedness when standing up quickly as it lowers blood pressure and I don't have high blood pressure. It has done wonders for my HbA1c and I am now at non-diabetic levels. What I would suggest, if you haven't already taken them up on the offer, would be to get a free trial of a CGM from Dexcom, Freestyle Libre and Allycgm so you can see how it is affecting your blood sugar levels.
