I know I said I was trying to use the postal services as much as possible but I have just ordered some D Mannose powder, some urine test strips and some probiotics from a company called Sweet Cures. I don't tend to get cystitis these days but I do like to have some handy if I feel a uti coming on. And I meant to buy some pro biotics from Holland and Barrett a few weeks ago but forgot. The test strips are more for the dog; she's still young and hasn't had a season yet. I worry about pyometra etc. If I have test strips I can test her urine if I'm concerned and tell the vet the result. So, along with my vitD, zinc, vit C [which I will only take if I get the virus] I feel that I'm doing everything I can to keep myself healthy. The lovely lady that I bought the zinc from has been delivering to her customers; the packet is in quarantine in the garage at the moment. She even did a shop for an elderly lady that was struggling to get supplies the other day. She's an angel!
