Headaches from Food

We had a company lunch today with our CTO and it was a Chinese restaurant. I don't like the Chinese food but I was hungry so I eat the lunch. After about 2-3 Hours I started having headaches. I thought it could be due to some outdoor noise. I took some tabs Panstan (Mefenamic acid). Usually whenever I take this drug the headaches go away. Than I slept for 2 hours and I woke up having the same headache and it worsened. I had some vomiting after that.

 

Could this be due to MSG or some food allergy. Right now I have taken a high dose of Panstan (Mefenamic acid) and still I'm having a headache.

 

I read somewhere to avoid MSG in Benzo withdrawal.

It's MSG. I learned  during my taper don't eat Chinese food. Ever..... BTW did your hair grow back yet?

Thanks for the Replay. The headaches lasted whole day and reduced the second day. I'm not going to eat Chinese food again. Strangely none of my office colleagues had the reaction to the food.

I guess Benzos has made me sensitive.

 

My hairs are still falling and they haven't grown back. I'm very concerned now. I don't want to lose them at this young age, as I'm still unmarried. :-( 

Don't worry.... Your hair will regrow.
