I'm on plan S and am just starting slowly with my supplements after the fast. I’ve been taking HCL for years. Is it okay to continue and for how long? I know at some point I will need to stop since we are trying to help our bodies make their own.

It's okay to continue taking HCL until you get to the re-seeding phase and it’s in your Digestzymes formula, so don’t double up. You may even need to do the HCL challenge after or during Phase 3, or during the transition phase to give your body a chance to learn how to produce HCL on its own again. At that point, you'll just maintain by adding in daily raw apple cider vinegar and the "ginger pickle". Then continue for about 4 weeks as you wean completely off the HCL, and hopefully, your restored parietal cells will be able to make it again.
