I have to laugh seeing what I posted back in September.
I am in my 3rd month of doing nights and it's really not so bad after all. At first I felt nauseous when waking up in the afternoon, but I learned what I could and couldn't eat at 3 a.m. and now it's much better. For example - don't eat spicy pasta or pizza in the middle of the night!
Also, I never schedule myself for 3 nights in a row, that would be insane for me. I do 1 on, 1 off, then 2 on and 3 off. Or vice versa - 2 on, 1 off, 1 on, 3 off. The 2 in a row is rough for me, so I couldn't fathom doing 3 in a row, I'd feel horrible. I know people that do it, though.
Long story short, I have adjusted really well, these past few weeks have been good. It's hard in the beginning, but don't give up to quickly, it takes time.
