Echoing everybody else who has replied - it is a very unpleasant drug to come off of! I was up to 187.5mg when I started to go off it - and it was painful going down the first 37.5mg! (Which I hadn't expected from such a tiny little pill!)
Drink lots of water. Things that have electrolytes in it. Chocolate. Those helped me through (okay, the chocolate was because I was pitying myself, but it DID help!)
