Query: Great Supplement!

For several years, I've been taking care of others in my family. I'm 70 years young but this last year, I felt like I needed to be taken care of,very tired and exhausted and didn't know how I could continue doing it. Came across Dr.Levy's books and articles. Purchased his books and Lypo-Spheric Vitamin C,at Amazon.com, one month ago. I've been taking 2 pkts. a day and have purchased more because I've received more energy and well-being for the day, sleep better at night taking this supplement. Thankfully feeling myself again!!!!!
