detoxing while on Candida plan

I have been very sick with lots of vague symptoms for the past six months. My doctors have no clue what's wrong but given my antibiotic history (having been on them MANY MANY times in my childhood and early adulthood, I'm now 26) I believe i must have Candida. 

I ordered the Candida force and the detox supplement yesterday. I read that I am supposed to sauna 6x a week and that is not financially feasible for me. 

Also, one of my symptoms is strong head pressure. (MRI, CT showed nothing.) when I sauna that pressure increases and lasts for a while after the sauna. (I had a sauna an hour ago and the pressure is still strong, but less strong than during the sauna). Other symptoms I get are drunk-feeling, tingles, numbness, fatigue and elevated heart rate. These symptoms have been improved lately (most likely due to consistently sticking with a Candida diet) but worsen after a sauna.

My questions are:

Should I be concerned about the increase in head pressure and other symptoms? Should I not be taking a sauna?

The lady who runs the sauna place says it's very important to replenish electrolytes after a sauna, but the electrolyte powder she (Orgain Organic Hydration) has coconut water and cane sugar. What other ways can I replenish my electrolytes?

What other options do I have to detoxify besides sauna? Will the plan still work without 6 saunas a week?
