DD2 had hideous nit infestation the other week, and she is nearly 15. Waist length, thick curly hair is unhelpful (and yes, I have taken the kitchen scissors to it before when she has had nits).
Spent today in a long workshop with inadequate lunch (only salads - I was starving by 3). All of the great and the good chose to attend the session I was chairing/facilitating, which initially made me quite nervous, but I told myself to MTFU, and it worked really well, as they all had lots to say, and all I had to do was steer them along to make sure we finished on time with a nice summing up of the way forward. I also delegated the writing up of the session to one of them, so win-win as far as I was concerned.
For those of you who are unable to tolerate NSAIDs orally, there is always the suppository route... 
My insomnia is due to a large cat who wants to sleep on me, preferably on my head. He gets sent back to his blankie, but as soon as he knows I am asleep, creeps up the bed.
