To cut a long story short, I was originally prescribed T3 many years ago and was well. A few years ago I was switched to levo and was not well. I have tried NDT and also NDT/T3 combo, eventually settling for T3 only and now feel much better.
I gradually increased my T3 dose and reached 125mcg at which point I was feeling pretty good - not 100% but so much better than on T4 of any kind. Last night, about 3 hours after my bedtime dose of 25mcg, I woke with sweats and a racing heart. Both are not something I typically experience. I have been on 125mcg for a while so I wasn't expecting this.
I was wondering if the reverse T3 had finally cleared and I was finally getting a shed-load of T3 into my cells all of a sudden. I did feel like I was hyper, from the descriptions I've heard of hyperthyroidism (from over-replacement). I slept only about 2 hours and while I was lying there I felt like I had just sprinted round the block several times.
Does anyone have any personal experience of this? I have read that this whole 'rT3 blocking the receptors' is a bit of a myth so I'm not quite sure what to believe.
As a result, because my body is clearly trying to tell me something, I have reduced my dose to 12.5mcg four times a day. I feel tired today but I am sure that is at least partly due to lack of sleep and a crazy day at work. I am going to stick with 50mcg for a few days and get some rest and see how I feel after that. My heart rate is much better today and much more regular again. My temperature was also nearly normal this morning, possibly from the clearance of that rT3. Even on 125mcg my temperature rarely reached more than 36.5 on a good day, unless I was ill. Today it was 36.8
Anyway, I would appreciate hearing from anyone who has been through this rT3 clearance, mythical or not. I do feel there is something in it even if it isn't the whole story.
I know I'm not well known for my brevity, but this isn't nearly as long as it could have been
