Your body is still going through withdraws even after 5 days. I find this with quitting any addiction. When I quit smoking for 3 years, the same thing happened. I had the same problem when I quit drinking for 10 years. It does pass. This time I was put on an antidepressant. It works great for me. Evened my emotions out. My doctor put me it on it for 3 months but I think I am going to stay on it for at least a year. Something for you to consider. Hang in there. It does get better. I am on day 39 today. Drink lots of fluids, take a walk, stay away from sugars and junk, take time to do something nice for yourself. Welcome to SR.
