I had an excellent appointment with my gp after receiving my 2nd set of results (posted previously) and she increased my levo from 50 to 75 mcg which I started taking last Saturday morning. Almost immediately I started to feel better - better than I've felt in years. My energy returned; sleep patterns were restored and sleep was restful; I could think clearly and my mood lifted. Even things I hadn't necessarily associated with low thyroid seem to improve: my eyesight was much clearer and my fasting blood sugar dropped from around 6.00 where it has been for some years, to below 5.3 (generally below 5). All this in a week. I was amazed, delighted and very thankful.
I was aware that towards the end of the week I was feeling a touch tired but it was a good tired - a healthy tired from being more active. However yesterday everything crashed. By lunchtime I knew I had to rest, which I did, but to no avail. All the old symptoms are back: exhaustion, so tired yet can't sleep, mood low, brain struggling to think (although this is not as bad as it was initially). The improvement in my sight has gone and I'm a mass of aches and pains, especially the lower back. Even my teeth, which had at one time become ridiculously sensitive, have reverted to that state again - I'd never connected that to the thyroid.
I'd appreciate any thoughts/encouragement. I was so surprised to feel such an improvement with the higher dose so quickly - I had assumed it would need 7-10 days to start having any effect. And to have it all vanish equally rapidly is very demoralising.
I recall reading somewhere that there can be a dip when first taking Levo or increasing the dose because the brain stops instructing the body to produce T4 itself, thinking there is enough hormone now. Might that be what is happening? If so, how long before things even out again?
I'd really appreciate any thoughts.
