Dancinggirl, I have only used Nexum for a week and before that over the counter Zantac and them for about a month, these headaches have been causing me a problem for years on and off, just got back grom the GP and she thinks its a tension headache, as I can get moody as well, I explained to her that certain smells affect me as well, and they radiate from my neck, she has given me Nortriptyline to try, she hopes they won't cause to many horrid side effects, we will see and has refered me for acupuncture, she says it isnt migraines, so we will see how I get on.....
