Traveling without bringing food with you is going to be close to impossible, I think, at least in my experience.
Also – you might want to stop the brown rice. It feeds candida.
This is a money suck though, for sure! I only work part time and I am always struggling to make ends meet, but I know that I never want to go through this again, so I just reallocate my resources to pay for my food and supplements and pray for miracles.
