It WAS overactive but thanks to radioactive Iodine it's now underactive .  I'm on the same med . I was told to take it at least 3 hrs. apart from my other meds or food so I take it 1st thing and take my other meds at work at break time when I eat .

 Yeah I don't recommend getting old !!  Not much in the way of options though .    I can't wait to be able to retire ! 

 I'd guess . 

So it literally 'fell off the back of a lorry'... 

Under- or over-active thyroid..? I'm under-active and have to take Levothyroxine every day. Still wouldn't get up at that silly time though, well I did many moons ago when I was young and foolish..! Now I'm old and even more foolish..! There aren't many things to be said in favour of getting old, but retirement is definitely one of them 

 I get up at 4:30 A.M. , Take my thyroid med , feed the kids , get myself together and off to work !

Nothing could possibly be so important as to get me out of bed at that ungodly hour 

 I installed this one : https://www.lighting-gallery.net/gallery/displayimage.php?album=5202&pos=288&pid=173786 by my neighbors fire pit/party area .  I found it on the side of the road still in the box where it had apparently fell off the back of a contractor's truck !

 I start work at 5 A.M. and I'm just amazed by the number of people who walk in the door either texting or talking on the phone!! What could possibly be so important that who need to communicate with someone that early ?

I am certain you would definitely notice you are carrying 180cm tube, as it is *extremely* bulky even compared to 150cm one...
