Where did you get diagnosed? Did you have headaches before all your mav started 5 years ago? My Dr said he feels I got this because had 18 aura migraines in 5 months and my brain didn't get a chance to recover so became irritated and caused this. Stress is definitely a big trigger for most people. Do you still stick to the diet? Are your symptoms exactly the same as 5 years ago?
I think you recovered for 5 years, you can definitely get back to recovery again. Don't let the anxiety take over. A Facebook page called anxiety no more really helped me at my worst points x
