At the very beginning of the Thomas Recipe there is a warning....that says if you are on an antidepressant, you should confer with
your dr. before taking l-tyrosine, 5HTP, or any other mood enhancer.
The Thomas Recipe also says you "may" take "up to
" 4000 mg...but to
scale up or down as needed. It also states if you get
the "coffee jitters" to
cut your dose down. There is even a statement about l-tyrosine causing the "runs".
