"i am just about to stop taking lithium for bipolar2 due to recent frightening side effects. no problems to start except thirsty, but lately had numb tingly arm which was scary,  i was told lithium level was 0.6 (should be fine) then a bit later had a hideous kind of fit, (i wrongly linked 2 a cocktail?) where i suddenly felt totally drugged but kind of clear headed, terrified, vision (but not eyes) flicking side to side v fast on and off for 2-3 hrs - horrifying. when i cld see i googled and very bad diseases like parkinson&#039;s came up. (eyes checked -fine) then next day lost ability to swallow at all for about 5 mins (dysfagia?) also terrifying. all 3 symptoms are signs of parkinson&#039;s but no thanks 2my gp i found they can also be effects from lithium. gutted"
