I suffered the same and went back to work... and that didn't work. You need to let your doctor know what is going on. Initially, I went back to work and then had to take 3 months off. I went back after 3 months because I didn't want to lose my job... and it was hard!!! My doctors had me on anti depressants when this first started because they said that my life would change and they were right.

You should not be drinking... that doesn't help, especially with the headaches.
