I took l-trytophan in 1989 and 1988. In 1989 I started with syptoms like muscle spasms and insomnia dry eyes dry mouth Severe Fatigue. My face got a red and dry rash on my cheeks. I have been suffering for 10 years . Does anyone know anything about this? I have been tested for Lupus and Sjogrens Syndrome but the blood test said no, even though I seem to have thier symtoms.
