try some Lavendar Oil on your pillowslip....works wonders.
Or put a wheat pack with lavendar on it under your head where you sleep.
I've tried all the alternative sleeping solutions possible and nothing works that's why I have resorted to drowsy anti-histamines. My GP wanted me to take Amitriptyline but I am reluctant to go on an antidpressent as I get horrible side effects (was on it for 4 years and the dry, swollen mouth never subsided). I now know it is my thyroid meds that control my sleep as I did sleep when I was on 20mg T3 but I looked awful in a morning with huge dark circles and had to survive on coffee all morning to try and do my work. I am wondering whether I was prescribled too high a dose of T3 as I have read some people can only tolerate 5mg T3 and I was on 20mg! I think when I start sleeping properly is when my body will be regulated on my thryoid meds and goodness knows when that will be.
Prolonged use of anti-histamines can actually aggravate the thyroid and should be avoided unless really neccesary.
I'd be asking for your meds to be re-evaluated again.
20mg T3 is a high dose.
I wouldve thought 5mg T3 to 50mg T4 would be sufficient.
T3 can keep you awake and can also make you hyper if it is too large a dose.
Question as to why he has you on 20mg T3.
