I am thinking that there might be some neurological disorder with the same symptomatology. Let me explain - for several years, I believed in the no alcohol rule. I no longer do, and try to remember to drink one glass of wine a day, which does not interact with Lithium in me in bad ways. But back when I didn't drink, I would, at parties or social functions on the job say that alcohol triggered my migraine attacks. It was not true, but it could have been true, and migraines, a neurological disorder rather than mental illness, carries no stigma with it. Likewise, if you request accommodations citing some unusual sensitivities rooted in something neurological... might be safer.
