Ex Input:
I have been struggling with lack of energy and weight gain since having a partial thyroidectomy 2 years ago. I am on a super low dose of levothyroxine and my blood work always comes back normal even though I still struggle with symptoms. thyroid support has changed my life. In one month of taking feel so much better- more energy and motivation to work out again.

I really wanted to like this product. I hate having to wash my hands free bras all the time, so I thought this product would cut that part out of my routine. I always find myself using this only when I don't have a hands free bra available because they're dirty. It takes way too much time to put on and set up the pump to the right spot to get a good flow going.
