I'm so happy to hear things are going better!!
With hypomania, the mineral supplement lithium orotate has worked wonders in controlling mine. It's not the drug lithium carbonate that has so many horrific side-effects--at least it did for me, but just an over-the-counter supplement that is much more readily absorbed by the body so you only need a little bit.
Here's a couple of articles on the subject. I take the lithium orotate mentioned here. The tablets say they're 120 mg of lithium, but are 4.5 mg of what's called elemental lithium that is what the body absorbs. I don't understand it fully as I'm not a scientist, but I can tell you that I've been using this for 4 years now, and my hypomania now consists of little more than being a bit wound up and not sleeping. When I started using the amino acid GABA to control the hypomania 9 years ago the racing thoughts stopped. I almost don't know I'm hypomanic unless I can't sleep, and then I take some extra lithium orotate and usually get a few hours of sleep. It's a huge blessing as I hate hypomania far more than I ever disliked be depressed as I could sleep with that.
