obesity
"I started Saxenda 2 weeks ago. The only side effect I have had is being tired all the time. I have lost 6 lbs with no exercise,  but now that my kids are back at school I'll be going to the gym. 
I find that I am not hungry for like 3 days, by the 4th day I am starving. I will be starting 1.8 in 2 days so hopefully that will stop the every couple day hunger."
