Hi! Carole,
You may take amitryptaline at night as usual.
The effect of Thyroxine 100 ug will wear off after some time.
Meanwhile from tomorrow take Thyroxine 50 ug for a week and increase it by 25 ug every week.
Gradual dosage will not cause you the problems you are facing right now.
Take some B-Complex pills. They will certainly help you.

When I was in Vegas almost 2 weeks ago I was laying out in the sun for about and hour when I started to feel as though I was going to faint; my heart began racing and my hands started shaking. I immediately started hydrating myself but that did not work so I went inside. After a little while I felt better and went about my day. The next day I attempted at laying out one more time but the same feeling started to come over me. After those times I stopped laying out in the direct sun and continued to enjoy my vacation. I stopped having these episodes . On the day I returned I went food shopping with my husband when I began feeling an episode come along. I told my husband I needed to get out of there because I felt like I was going to faint. I went home, laid in my bed and began to hydrate myself once again. The next day I called out sick from work and went to the Urgent Care where I live to see a doctor immediately. The doctor did an EKG on me as well as blood work but could not find anything. He did state that on my EKG there was a line that was a little off but that it could be normal for me. It did not cause him much concern but he did state to follow-up with a Cariologist which I will do so. Since that point which was a week ago exactly, I have felt slightly better but not 100%. I do not feel the way I normally do. I ve had a couple of instances were I feel like I m about to have an episodes but kind of talk myself through it. A couple of people have told me that I am suffering from panic attacks. The two people that told me this are people that suffered from them and know first hand. Funny thing is my husband thought the same thing. Could this be what I am feeling?

I am a 27 y.o. female in decent health. I have struggled with panic attacks and disorder for 12 years. I have only taken pills for it once, two years ago. My mother recently passed away and i have been having the ongoing symptoms of panic (shortness of breath, racing heart, heart feels like its going to flop out of my chest) for the past month. It comes and goes, and i have only had a couple of full blown attacks (hyperventalating, crying, basic melt down) twice. I have had these symptoms before and two years ago when i had them, i took myself to the emergency room again. Once again they said it was just stress and the panic disorder. I asked several times if they were sure my heart was ok and they said yes. So, my question...I am supposed to take my daughter to an amusement park tomorrow, and i suddenly am terrified about going on coasters, because of the way my heart has been latley. So, my hightened anxiety about riding the coasters makes me more nervous and then more paniced. Although i have been told before that there is nothing really wrong with my heart, do you think riding the roller coasters would be dangerous? Please note that i love roller coasters and have ridden them every summer for the past 8 years in spite of my anxiety. Do you think that my sensitivity regarding my mother and fear of my own mortality is making me feel worse, or should i really be concerned about my heart?

My mother is 89 and on hospice care for advanced A.D. she has developed, over past year, an indentation on the top of her skull running left to right about three inches back from the front of the scalp. She has several large nodules on her thyroid, but her endocrinologist declined to pursue with needle biopsy or surgery due to her age and advanced disease, A.D. what do you think could be the cause of the changes in the top of her skull, indentation. She also has had significant loss in brain mass in past 12 years per MRI studies ren years apart.

My psychiatrist added 25 mcg of liothyronine, I started taking it Thursday 3-19, to be increased to 50 mcg after one week to augment my depression that has been resistent to other antidepressants. I don t have enough energy to leave the sofa. I also have panic disorder. I have gained about 35 lbs. in about nine months. I m nervous after reading some of the reviews. Should I be. How long can I safely take this medication. Will my thyroid stop producing the harmone naturally if I stay on this medication? When I come off will my thyroid be normal? I have very high hopes that this will increase my metabolism and give me the energy I m lacking and aid in my depression. Thank you
