I had my thyroid glands removed in 2009 Could the wrong dosis of thyroxine be causing me excessive sweating in bed??

Yes it can. Yes it can.If you are receiving more replacement hormone than you really need it will make you hyperthyroid and that can cause you to sweat in bed Consult your doctor or endocrinologist and get you blood tested for thyroid profile to see if you need to reduce the dose of your thyroid hormone.
