Hello all, I've been on lithium for 4 years and been on 1800 mg (900 twice a day) for maybe 3 out of the 4 years. It's taken some finagling to get everything right, but it really works. Without it I am severely depressed and suicidal.

However, after reading through some other posts on lithium I'm pretty concerned.

First of all, my blood tests always read somewhere around 1.2-1.4. I show no signs of lithium toxicity ever, but I just heard that over 1.0 is bad?? No one ever told me this! My blood tests have consistently been about 1.2 for years.

Secondly, I am starting to experience more stomach pain than I ever did before. Usually, if I take my lithium with a meal I'm fine, absolutely no stomach upset. But I'm suddenly experiencing moderate stomach pain and nausea after my doses no matter what.

This medication has done wonders for my mental health, but I am really worried what it is doing to my body. 

Any input? I am about to leave the country for a few months and don't have immediate access to my doctor at the moment, and I'm just wondering if my worries are reasonable.
