Adventure that was my worry with jeans just now too, I have a couple of pairs of Superdry skinny jeans that have so much Lycra in them and sit so low I've sort of designated them as under bump for now.
I can no longer fit I'm my normal leggings, feel like they cut me in half so I'm sticking to maternity tights, dresses and chunky jumpers for now (after washing Boots tights seem to have fared better than ASOS but that might also be 60 vs 40 denier)
Gurtie you sound like me a couple of weeks ago, few things fresh lemon slices and a spoonful of honey in boiling water works well, I also went to the pharmacy and the honey, lemon & glycerin cough/sore throat medicine is fine as are locket type throat sweets, I took paracetamol to get me to sleep at night and although it's ok to take I didn't want to take it all the time because it reduces the effect and I wanted it to knock me out
I'm still being sick in the morning and in the evening, so much for hitting the magic 12 weeks and it all going away (I realise this was a forlorn hope!) still constantly starving as well although feeling virtuous today as I managed to cut up some carrot sticks to munch on rather than biscuits 
Crazy I'm amazed that you have that much energy I keep looking guiltily at my yoga mat and road bike on the turbo trainer, although I think if I did any yoga now I'd probably fall asleep in most of the poses! We went for a 2 hour walk with the dogs on Sunday and I was nearly asleep in the car on the way home.
