Levoxyl and libido

I was prescribed levothyroxine by my nurse practitioner for a "slightly" underactive thyroid. I have experienced at times, headaches (feeling like the top of my head is going to blow off); stomach problems, cramping, loose stools; anxiety, sleeplessness, fatigue and a lowered libido. I am prescribed .50 mcg, but I took that dose for 2 months and then lowered my daily dose, myself to .25 mcg. I felt better, but still tired. I didn't tell my NP that I lowered my dose. After a month or so, I upped it again, just because I still felt tired. I have been on the full dose, once again, for a month. I still have some of the previous symptoms, but am due for a blood test this month to see where my levels are at. If they are close to being correct, I am going to ask her to lower my dose or stop it all together and try exercising more. I don't know that this is a horrible drug, but I am sure that it is not something to mess around with, if you don't absolutely need to be taking it.

Ihave been on Levoxyl for about 2 1/2 yrs now. I am now taking 100mg. I ache in my hips and arms and sometimes have a sore throat. I have gained weight (about 20lbs) and feel confused and almost like a panic attack at times. My vision is shot and now I'm going for laser surgery. My libido have been effected by this too and that has caused problems. I have not lost any hair but my hands swell from time to time. Please let me know if anyone has any suggestion for this. I don't want to stop taking it for fear something will happen.
