So, I recently began taking daily probiotic supplement. The Garden of Life brand.
Things are moving along beautifully if you know what I mean. As someone who has suffered with irregularity all my life regardless of diet, this is a pretty big deal to me.

However, with about $30 a month for that supplement alone it really adds up and I'd imagine it would not be financially sustainable for me long-term.

My question I suppose is: If the gut flora gets balanced, or repaired - for the lack of a better term, is it really necessary to continue taking probiotics. Does it get repaired over time at all?
Basically, is this something that needs to be taken continuously?

I know another option is consuming fermented foods often, but my question is specifically about probiotics.
So, what's your experience with them?
