That would depend entirely on if you actually needed the extra 25mcg or not!

If you dont need it, you could go hyper which is just as dangerous if not more so that being hypo

Well think my GP needs to reduse my dosage not feeling to good today but like i said my appointments not for 2 weeks so will have to put up with it till then just hope i dont get worse.Why is it you have to wait so long to see your GP it does my head in.

If you have been hyper, the transition to hypo does make you feel really unwell, it only lasts a couple of days though, then it settles down.

Not saying you were or are hyper, just IF!

Yes the waiting is a pain, but if they are waiting for levels to stabalise before retesting, then it has to be done mores the pity.

Hope you feel better soon

Do you happen to have your latest blood test results? If your T4 and T3 are not too high you are unlikely to have any problems but you should monitor yourself closely, especially your temperature and pulse, to make sure you are not going hyper. If you went hyper you would likely notice symptoms. If you T3 is near the top of the range, I wouldn't recommend increasing as that would possibly make you hyper.

I have never asked for my results but i know my body temperature is all over the place at the mo my hands are either really hot or really cold and can feel my whole body pulsating more my arms than anything,Its just a good job its my day off didnt sleep to well.

If you feel you are taking too much you could try to take a smaller dose for a couple of days and see how you feel.

Are you actually taking your temperature or just going by how you feel? If you have a thermometer it would be worth taking your temperature every 3 hours during the day. If it is consistently on the low side, you are likely hypo. If it is high you are probably hyper. It will likely be lower in the morning, rising to a high (should be around 37 degrees) late afternoon/early evening and maybe dropping off a little before bed. If you average these readings for each day and you find that this average fluctuates a lot then you might have a problem with low or high cortisol.

I hope you find the answer and feel better soon.

If Peggy has stressed adrenals then the temperatures will be all over the place and taking more meds could oeasily make her feel worse, much worse. Why not follow temperature averaging as per drrind.com? Or consider a Saliva adrenal test?

Is there a version of the Dr Rind chart in degrees Celsius? I can only find the Fahrenheit one.

Thanks for clearing that up. I was just explaining why taking temperature is useful and how it works, in a hypothetical way. I wasn't suggesting that taking more would be a good idea in fletch27's case. I can see how it appears that way though, and I should have worded it better, so thanks for intervening :)

interestingly I made my own graph to monitor my temp and I found it more helpful to have this to compare too as I plotted my variation. I was crashing around all over the place when I was really ill but found it reassuring to see things stabilize and follow the norm pattern in recovery even if I didn't always 'hit the mark.

I didn't record my pulse because I was aware of that increase as my temperature rose.

It does, however, need to be taken over days to see the variation/stabilization after recovery.
