Hi, I've never posted on here before but know there are lots of wise folk who may be able to help... I've just been diagnosed with an underactive thyroid and started on 50mc Levothyroxine, with a blood test in 6 weeks to see how levels are going. I was wondering how long it took before effects begin to kick in. Assume I am on starter dose which is pretty low. Will I be Superwoman by start of term?? Nice thought!! Also, have heard lots of conflicting advice about actually taking dose. My mum was on same drug and made a big thing of getting up early to take it on empty stomach, only with water, and not eating for next 30 minutes. Aargh - term time early morning schedule does not currently allow for tablet taking time, but will obviusly make adjustments if necessary. Suppose I could use that extra 30 mins to practise yoga, do extra planning, walk the dog... Sorry for long post.
