My pdoc finally agreed that I am bipolar and now that he is convinced, he started me on lithium. It has been going great I feel better than I have for months and months, but I have tremors from the lithium. Any suggestions to help laugh them off in public without telling the world I'm on lithium?


Uhm, why do you have to tell the world you are on Lithium?
A lot of meds, for different things, can cause tremors or tremoring.
A lot of different neurological disorders can also.
It isn't "lithium" only and unless you actually draw attention to it, doubt few will come right out and ask why you are tremoring.
I mean folks withdrawing from addiction have some sort of tremoring.
I've had a lot of different side effects from meds over the years and tremoring is & was the least of mine. Try explaining why your tongue inadvertanly pokes out or your arm jerks and swings on their own, or your head is trying to roll backwards down your back due to a convulsive muscle spasming.
If someone directly asks, you could act like you haven't a clue what they are saying and then go "oohh, so I am, maybe I should get that checked out".
