Hammering so hard symptoms and conditions

After reading everyones comments, I was so relieved to see that it wasn't "just me". I have been on levoxyl 100 for about 2 months now. For the past month I have been very nauseated, have sore joints and muscles, severe headaches, dizziness, rapid pulse, I am tired, but I feel like My head and heart are going to burst. My legs are weak too. It was just last night that I woke up gasping, and my heart was hammering so hard I could feel it in my head and neck. My arms and legs were so numb like pins and needles. I thought i would pass out. I was so scared, I've never been so scared and I even woke my husband up and told him I thought I needed to go to the ER. I did'nt know what to do. I felt like I was having a heart attack, and I even got dressed and did not sleep the whole night cause I was too scared to sleep. Today I went into the doctor and they said it was probly too high a dose and cut me down to 50. they said I cant take it for 2 days, to let the high amounts out of my system, but I don't know if I want to take it anymore. I am only 25 and I feel horrible: older. I don't want to do anything anymore, I'm tired and ill, and I have gained 5 pounds. I usually take herbs for every kind of illness, but I don't know if there is any alternative to this horrible pill. I saw some of you mention ARMOUR thyroid. Is this a natural alternative? Can anyone give me more information?? I am really tired right now, cause I have only had about an hour of sleep since 12:30am this morning, But im scared to sleep, lest I have a repeat of last night. I thought I would have a stroke or heart attack. Im glad I found this page. It is nice to know it isnt just me.
