I have been on levoxyl for about 6 weeks now. I was placed on this medication after I had my daughter 8 months ago. I was losing my hair and they (the OB and GP) ordered some lab work to be completed - my thyroid was a bit under active. I read some where that this occasional happens after pregnancy, but it would eventually correct itself and all should be good after a few months. (This happend with my first pregnancy also - but they never ordered any labs to be completed). To my dismay, they placed me on this medication. I noticed for the first 2-3 weeks sever fatigue, I would be motivated in the am, but by the afternoon I was exhausted and needed to nap. I also tend to have nervousness and anxiety attacks - symptoms that I have never experience prior to being on this medication. Lastly, there seems to be times where I feel like I have drank 500 cups of coffee and have a huge high, then crash and have a huge low. Anyone else??
