On getting from SAD to paleo:

The way I have been most successful is to give up a category of food, let my
body rebalance, and then go for the next.  You can decide what order to give
them up in.  "Cold turkey" is great for cigarettes, but not for food.
Your body
needs to get used to the changes, and adapt your digestion..
