My personal experience with lithium has been similar to what is described in the medical literature. Low-dosage lithium is effective for depression. 300 mg/day is my sweet spot. If I go to 450 mg/day or higher, I relapse and experience cognitive blunting and a mixture of amotivation and passivity.
It makes sense to start low and give 300 mg/day no longer than 2 weeks before moving up. Increase by no more than 150 mg/day, or you might miss your sweet spot. At 300 mg/day, lithium is unlikely to affect thyroid and kidney function. If upon starting low-dosage lithium at 300 mg/day, you feel any improvement, and going up to 1200 mg/day is ineffective, just keep taking 300-450 mg/day. If nothing else, it might provide prophylaxis against Alzheimer's Disease. The best argument for keeping lithium on board is that it might be a critical component your future combination drug therapies.
Blood levels are irrelevant using lithium this way. I would be surprised if mine were higher than 0.2.

Recent studies have discovered a bimodal dosage-response curve for lithium. It has opposite effects on glutamate levels in the hippocampus at low versus high dosages.

These are associations seen in some studies:
Low glutamate is associated with depression
High glutamate is associated with mania.
