"started saxenda 3 weeks ago. first week slight nausea.  a little dry mouth. need to increase fluids more than likely. i have struggled my whole life with my weight. even started process for gastric sleeve and backed out at the end. i have lost 14 lbs in 19days. 1800 calorie diet. most days under that. i don&#039;t feel hungry. don&#039;t crave sweets like i did. and diet coke makes me nausea. i am very hopeful. the warning for thyroid cancer does somewhat alarm me. but planning maybe to stay on saxenda 6 months to 1 year. i start 3 mg in 2days. i have be impressed with results."
