I had nothing but trouble with Hashimoto's from the start more than 25 years ago. I'm now 59.
One thing that helped heart related issues was a diuretic. Lasix or similar was really good at reducing water retention due to my (then) new-found inability to process salty foods. Doctors said I was having a panic attack at 2AM. However I would be sound asleep, having a wonderful dream, and my heart rate would hit the stratosphere and wake me up. I was not panicked about anything, and had no trouble falling back asleep. Sometimes I'd simply go for a short walk to settle my heart rate down, and then sleep until morning. Finally my cardiologist figured it out.
As I've mentioned on these forums before, I don't do well on T4 hormones, and am now on T3 only, which I take 5-6x per day. I can easily take the amount of thyroid hormone I need without taking too much or too little. I do it by "symptoms", if I am sweating too much, I can cut back a bit, and if I am unusually cold, I can take a touch more. Pretty easy for me to deal with. Considering all the trouble I've had.
