Do you have someone, in particular, you turn to for advice on health, in particular healthy eating?
Before I head to my doctor, I check the Mayo Clinic website. I've always heard WebMD wasn't a great source.
I buy online almost everything, including vitamins and medications https://www.canadadrugsdirect.com/products/viagra. When choosing an online store or pharmacy, make sure to pay attention to reviews. I also usually look for general info about the company, it helps to find the best option.
