"i&#039;ve been on saxenda for 1 week so far @ 0.6mg. i&#039;ve lost 4lbs. i&#039;ve had no side effects, only thing i can say is that my mouth is dry and i&#039;m thirsty more than usual. otherwise no side effects, i take the injection around 7pm-9pm. last night i just upped the dose to 1.2mg and i&#039;m more thirsty so i just carry a large water bottle with me now."
