Turtleneck symptoms and conditions

As most of you, my TSH always came back normal/border line as well. However, due to all of my symptoms - every single one for Hypothyroid - they went ahead and did an ultrasound. I had a nodule 15mm x 5mm on the left lobe and 5mm x 4mm on the right. Because I had the constant "turtleneck" feeling around my throat, it was getting hard to swallow and sounded like I was an 11 year old boy gowing through puberty again, because of the hoarseness, I had Total Thyroidectomy last week. My surgeon put me on 150mg of Synthroid. So far so good with the side effects, granted it's only been 6 days. I actually have more energy, and a decrease in appetite. I've already lost 5 lbs. Not real sure if my energy level has gone up because I no longer have a thyroid to bring it down or if it is from the medication. Either way I hope my side effects stay as they are, I could stand to lose another 50 lbs - haha
