Lithium
"I have been taking Lithium, 1000g a day, for the past 39 + 1/2 years.  I always drink a lot of water daily, + wee a lot or course.  I have experiences tremours when water intake is low. I initially had hand tremor and some thinning hair.  I have been taking 2000g of fish oil for the past 15 years and have recently started epilim to fine tune my short manic episodes.  Lithium has been the saviour of my life many years ago after 2 manic episodes in one year.  I take blood tests yearly or every 2 years ( if I forget, )to determine effect/normality of the internal organs in relation to Lithium.  Resisting gambling, drugs ( smoking, ) and limiting alcohol has given me a lovely wife and seeing my now 2 adult sons grow up."
