A friend of mine's PDOC always says this:

ANY drug can affect ANY person, ANY way.

Of course there are some side effects etc. that are more likely than others, but basically it is different for everyone. I have never gained a pound on any BP drug and I know people (including on this forum) who have gained hundreds of pounds on these drugs.

I don't think fish oil is a solution for the long term, but if it is working for you today, then that is great. I hope that as soon as you begin to feel manic again you go to your Pdoc and discuss other options besides lithium....because there are many other drugs.

Best of luck to you and everyone else as we try to figure out the best way to treat our illnesses which have many similarities and many differences.

PS I tried taking fish oil capsules for a while but I had these really gross fishy burps and I couldn't take it!
