Hyperthyroidism

I have no thyroid and to prevent cancer coming back (the cysts was golf ball size) I need to be high. I see a specialist every 6 months. I was low because I was forgetting to take the tablets due to my boys being sick now my levels are back up.

My heart rate when I am the level they like rests at about 90 and when I stand it can jump 160ish, when I was pregnant it was resting at 120 and jumping over 180 for no reason. The drs thought i had a clot so I was put onto blood thinners, it was the strain of the twins on my heart plus I was thyroid toxic without being overdosed on thyroxine (eyes would pop out when following a finger with my eyes). currently I am getting no chest pain.

I was diagnosed with bi polar because on the mania caused by having high thyroid levels believe me I hate this I would love nothing more than to be within what is normal but if I go there the cancer may come back. Seriously I will have that risk my entire life because of the size of the cyst. I will NEVER be able to let up. My old oncologist wanted me to see him for the rest of my life and never be handed over to a gp because gps would see me being high and freak out and drop my medication level resulting in me being put at risk. Yeah it is great that the weight is coming off but I am not jumping for joy because it is scary fast, honestly think if I starved myself it wouldn't come off as fast as this! I'm not using it to loose weight I am shocked at home much I have lost. the cancer i had is easy to treat if you catch it in time and they were maybe a week off getting it too late, it had just started hitting my lymph nodes and after that it spreads. I say the cyst was big but the cancer spread beyond the cyst

I have never been as over weight as I was and never dieting with my levels high which is why I am wondering if anyone knows if it can strip it off you so fast. normally when I am high (lower end of high) I am 73kg and I eat like carbs are about to disappear from the world and don't gain.
