I was so hoping that the lemon juice might be your answer! It totally turned me around. Bless it!
I didn't know what Oxypowder is. Thanks for telling me.
I don't know if this would help you, but lately I've been having good fortune with simply making a statement that I will find a solution to a problem, and then forgetting about it.
Somehow an answer just appears, as if by magic. This has been happening in shorter and shorter periods of time. Saves me oodles of mental effort. (Grin.)
Every best wish for joyous good health throughout your household.
Thanks for sharing your story. We look forward to your success.
