I'm sorry to hear you're detoxing so badly. I would recommend what the others advise but add you might try the pulse-dosing. That means stop Iodine for 48 hours while you continue the salt loading. Stopping Iodine will rest your kidneys and liver and flush out the toxins.
Also, you mention "bladder infections." I'm betting these are not actual bladder infections with bacteria --but a common side effect of bromide detox that's actually a spasm in the urethra or ureter. I've had them myself both when I started Iodine and when I raised my dosage from 50mg to 75 mg. The bromide dumped into my urine and I hadn't taken enough water.
I sympathize about your brain fog. The state revoked my driving license for bad driving. I once walked around the city for two hours not realizing I had a wooden hanger inside my blazer. Only an old man had the courage to point it out. You will get through this! Just use the tips of pulse-dosing and salt loading.
Could you write back in a few days to let us know how you are?
