Pretty par for the course, I would say. I have known people who gutted it out and went to work, but if you can take Monday-Tuesday off it will help. 3 for me was the worst, and 4, but 4 was bearable.
Keep posting and good for you for kicking this awful habit! I'll be there for you as much as I can (I prowl a lot at night). DO NOT TRY TO REFILL SCRIPT!! You will just have to do it all over again. Are you drinking lots of water? And all I could keep down in the way of food was crackers. Keep them at hand and nibble away. It will help pass the time and you do need something in your stomach.
