I am having the exact same side effects. I have an 11 month old son and I can not lose my pregnancy weight. I eat great, I go to the gym 3-5 days a week and work out for an hour each time. I am always hungry and my energy is completely gone. I fall asleep every night by 9- 10 at the latest. My sex drive is non existant! I have scheduled to have it taken out in 2 weeks, I will let you know how it goes after that.
