I am on Lithium Carbonate 600 mg.

I bought Lithium Orotate from Swanson Brand and start taking 5 pills of 5 mg a day.

But I am facing sleepiness and slight head Ache during work.

With Lithium Carbonate I was completely perfect with very slight brain fog.

Changing the brand would make a difference or should I switch back to Lithium carbonate. What do you guys say?
