The tablets are magnesium phosphate 100mg, and have 25 mg potassium phosphate. I am taking 4 a day, so that is 400/100mg. I seem to be doing better. I am not sure what dose I should be taking though, I am just following the bottles direction.

I am not sure that I should take quinine though (other than with gin!) as I am on 400mg of hydroxychloroquine already for my lupus. As the side effects can be pretty grave (damage to vision) I wouldn't like to increase my intake of quinine without talking to my rheumie.

Thanks guys, you are always so helpful.
