Hello Santiq
Welcome to our beloved Forum
i have experienced this too, it comes and goes for me and iv'e never worked out why lol
today for example no yawning at all, weird huh?
everyone is different of course and the side effects of Duromine effect some and not others,
the yawning thing is something iv'e never worried about
it sounds like you are achieving some nice things though with your eating habits well done!
a piece of advice i like to give is always skip a day here and there,
you will find that on your days off you still have the Magic..
Hugs
