Is this normal?

Hi all, well I've adopted my change of lifestyle as directed by my thyroid support group leader, however a few things have been bothering me lately.

I've now changed my thyroxine dose to 100mcg and take this at night as I get a small "buzz" within a short space of time of taking it during the day. However although I took it before bedtime last night I woke up during the early hours of the morning and found it very hard to go back to sleep. The thyroxine wouldn't have done that as it's only happened once, surely? If so should I go back to my GP about it? I usually sleep all the way through from say, 11pm to 7:30am, so for me to get insomnia is unheard of. I don't drink any caffeine after 8pm either, so I know it's not a caffeine issue.

I've upped my water intake, eaten more fruit and veg and have been off sweets and chocolate since Sunday, however I had very bad constipation this morning. I have no idea why.

I'm pretty sure it's my body's way of saying it doesn't want to adapt, but I don't know what I'm doing wrong.

Can anyone advise?

Maybe your trying to change to many things all at once instead of taking it in stages. Did you just wake up last night or did you wake up to go to the toilet or something. If I increased my water intake I would be awake 2 or 3 times a night to go to the loo.

Your constipation could well be down to the drastic change in diet. I'm not saying that you should start eating chocolate and sweet again but maybe you should have cut down bit by bit instead of doing a total eating habit change all in one go. Your body, especially your stomach, must be wondering what the hell is going on all of a sudden hence the constipation.

It can take up to a week for the body to adjust to taking your levo at bedtime - some people report bad headaches, some say it can disturb their sleep so you might need to give it a little longer before you decide if its for you.

Hi Moggie, thanks for your reply.

I just woke up last night and that was it.

I thought with the digestive issues it wouldn't take that long at all. I'm not even passing that much urine despite drinking more water. Would that mean I was slightly dehydrated without knowing it?

Thanks for your answer.
