What do you mean by feeling like day 1?
I have no idea how I will feel at 4 years. At nearly 4 months, I had a night of sweating all night last week, headaches and massive anxiety. I would have loved a drink, because this is how \I have resolved this kind of problem. It could be PAWS, premenopause, the flu. But it is not the despair I felt on day 1 (or day 10) when I had no clue if I was even going to make it 24 more hours.
Is it really like day 1?
