SIBO, Candida...Gas & Bloating

I have Candida and have tried every kind of probiotic out there and they cause me to bloat w/ lots of gas that never gets better and makes my IBS-C worsen. My Dr thinks that I might also have bacteria overgrowth in my intestines as well. Recc Antibiotics , rifaximin(xifaxan), and I really don't want to take Antibiotics .

Anything else to take to help the gas and bloating?? Can too much good bacteria cause this problem as well?

Anything natural to kill the bacteria overgrowth??

I have tried things like GSE, Olive Leaf, CS, Oregano etc, as well as anti-candida stuff w/o much success. Thought maybe I would try a zapper, maybe it could be parasites. Did try colon cleansing, helped w/ my constipation but it also caused increased bloating as well.

Does anyone know if good bacteria is bad for bacteria overgrowth?

I have read conflicting statements. Some say not to take probiotics when one has bacteria overgrowth, some say it is good to take.
