Levoxyl and heart rate

I started taking thyroxine about 6 weeks ago - i went to the doc with tingling fingers, bloods showed tsh 34 so doc gave me 50mg thyroxine. Felt awful within a few days i was getting palpitations and felt like my skin was crawling. I couldn't bear even the slightest noise. I had diarrhea (cant spell) fast heart rate, the shakes and couldn't handle lots of people in a room. I am a teacher so it became difficult for me to work. I went up to 100 it got worse, until in the end I decided to stop them.
I am going to wait and see but I would rather be hypo than have these symptoms, my doc said you will feel great soon, pah what a load of c%%%

I have been on Levoxyl for about 9 years and have felt awful. I have had weight loss, dry hair, thinning hair,dry skin, muscle aches, migraines and the list goes on. I just got out of the hospital Monday after 4 days of testing of my heart and lungs. I was admitted for racing heart. The doctor's conclusion was anxiety! They said that Levoxyl has nothing to do with my rapid heart rate. The endocrinologist prescribed taking levoxyl .050 on day and .075 the next also a beta blocker, Xanax and Zoloft. I can not take any of these meds b/c they make it almost worse. I KNOW it is not Anxiety and it from the Levoxyl but what do I do?? I am a mess right now can not be in this condition with four young kids and a husband. None of the doctors would say it was the Levoxyl and instead prescribed more and told me to check up with blood work in 6 weeks. I took the .050 yesterday around noon and by 7:30pm my heart rate picked up again and continued until 4:30 this morning. I can not sleep more then 2 hours at a time and wakeup feeling like I am crawling out of my skin. PLEASE let me know of any solutions.

I had been on Synthroid for years and felt fine. Switched to Levoxyl and felt the same. Then they put me on Levothyroxine and still feel fine. Then they upped me from .125 to .150 and I have felt worse since. A faster heart rate, dizziness, and always blacking out.
