then when I went to university (i ate a meal ) I fell I couldn't sit in class and I couldn't hold my head and need move my body
2 week after, I fell I am hungry after I ate a meal (before that my stomach was empty and I fell good)
I had this fell in the night and stay awake until 2 am for eating.
I went to Internist(digestive) and he did prescribe endoscopy and I did it and he said it's ok
he said you must go to Psychiatrist
I went to Neurologist and he did prescribe MRI and I did it and he said it's OK
I go to Psychiatrist and Psychologist but my problem not solved
