"i&#039;ve been on saxenda for 4 weeks after trying unsuccessfully for about 12 months to lose any weight at all. i&#039;ve lost 6 pounds, which is awesome for me. i just started the 3.0 dose this week, so i haven&#039;t even been at full efficacy. the side effects have been mild and tolerable... a little nausea after each bump in dose, some heartburn, and fatigue. they seem to be getting better the longer i am on the medicine. i got a discount card from the saxenda website that keeps my co-pay at $30."
