Lowering my lithium dosage what were your side effects if you had

[u/Fragrant-Custard9737]

24 female here I’ve been on lithium since I was 17 although it did increase after I got Covid and my other medication stopped working. It took a couple years for me to finally get my bearings back and be doing a lot better. I talked with my psychiatrist and we both agreed that it was safe to start lowering my lithium since I take 600 mg twice a day so 1200 overall and he prescribed me a 450 twice a day so 900 mg daily. I started my first round this morning of the 450 and I feel a a little foggy, but I haven’t started to go into an emotional depression, had a little bit of manic energy, but nothing extreme and I can’t really focus all that great at the moment but overall so far it’s been Ok. Because I’m doing this of my own volition and my psychiatrist told me that I’m not in any danger. I am allowed to go back up on the dosage if I find that, I don’t like this I’ve been trying hard to see if I could find any symptoms for lowering the dosage of lithium, but all I’m finding is lithium withdrawal symptoms, which is not exactly what I’m going through or at least I have an experience them all the way yet has anybody had experience with this? I’d love to know.
I should add that lithium has helped me a lot. I know some people have not had great reactions to it but overall, I haven’t had any major issues with my lithium the way I know a lot of people do. The main thing is I don’t want to get to a point where I might have to lower it and I’m not in a good place too anymore because even though it hasn’t been affecting me, I do know know that 1200 a day is a lot even if as my doctor told me it has just now started to register that I’m taking it in my blood work report, it wasn’t even showing up in my results until I got to 1200mg and even now it’s on the much lower end of the safety range
