This may not be helpful but, for me, but when I am at 900mg of lithium, my Dr. has me take 600mg in the evening and 300mg in the morning.
Of course you should check with your Dr, nurseline, or pharmacist, but from what I understand, doses over 600mg should be split into 2 doses 12 hours apart. *I* would not hesitate to use the 300mg pills over the weekend. You willl have to make that choice for yourself.
