I feel better that I AM NOT ALONE!I had the mirena for 2 1/2 years. I should have went with my gut..not to get it. At first it was okay..then after 2 years i gained 15 lbs. Im on my 3rd period, and the crash is horrible. Im so tired i can barely keep my eyes open. I get hot flashes, anxiety, insomnia, fatigue, heart feels weird too. I dont wanna get up and do anything. I feel like a zomby. I feel so bad for my husband and kids, Im so irritated, and its not their fault. Any one have these same symptoms? Im soo scared if this is how my periods are going to be. My OB says the mirena has nothing to do with the way im feeling, but my GP says different. He believes me and said this is ALL from the Mirena. He said give it time, it will pass. Eat right, and exercise.
