I started LDN three weeks ago, .5 mls and am now taking 1.5 mls. I have noticed a big difference. I was on 2 1/4 grains NDT. Last week I started feeling very 'hyper', thyroid- wise, (palps, sweats, high pulse), so missed a couple of days and then re-introduced at 1 1/2 grains. I also missed the LDN for a couple of days and took 1.5 mls LDN last night. Today I am not feeling great, tired, gut ache, headache. I am not sure if this is too much LDN or not enough NDT and can't decide what to do. I am not seeing my FP until next Thursday. I have seen a lot of general comments online about the possibility of having to reduce NDT, but can't find anything in detail. What has worked for you? Any suggestions.
