Wayne, you may try this combo- it does not work for everyone, but there is lot of good feedback:
1. Preload selenium for couple of weeks up to 400 mcg
2. Add iodine* (lugol has a good reputation and iodoral is not bad) not sure about max dosage, I would keep it at lower, maybe 200 mcg
3.Add l-tyrosine (mind you that l-tyrosine can convert to dopamine and also norepinephrine, and if it goes too much to norepinephrine person may feel jittery, restless) 1-2 grams
4. Also add Vitamin B6 (as pyridoxal 5’-phosphate) 100mcg
5. Some say its good to add Tryptophan (up to 2gr)- at night to "calm down" if there are issues from l-tyrosine
