Derek, anyone?... need some Sauerkraut advice please.

I too am in Australia (NSW) and I grew up on Sauerkraut as my family are originally from Latvia. As a child I never had major tummy complaints and although I was constantly on Antibiotics I never had Candida problems until my teens (I am 33 now) and coincidentally I didn't eat much Sauerkraut anymore but the usual 'teen diet' of junk. Where in Australia do I get a good Sauerkraut as I am too weak still to cook regularly etc. Will Sauerkraut give me diarrhea I have a tendency to get it right now (Shelleycat said this could be Spirulina causing die-off etc). As I am still building up my adrenals after exhaustion I avoid anything that will drive my body too hard. Please tell me Sauerkraut can be a safe food for me?
