Hi Courtney,
If it is Vitamin D, the best I have found is a fish oil supplement. It is Carlsons, lemon flavored. I had a doctor recommend it once because he found me to be low in Vitamin D.
I only used it one time as it is expensive but I thought the lemon flavor made it a yummy addition to my salad.
You can find it at health food stores, I know the Whole Foods store near me carries it.
I get tired a lot too and have been tired myself lately, also really dizzy for the last month, which I hate. I haven't had this kind of dizzy spell for over 2 years now. I think a lot of it is stress for me so I am trying to stay relaxed. Going to doctors is not an option financially for me and besides they usually tell me nothing is wrong or I am depressed, and at almost $100 it does not seem worth the price to just hear that again.
Also, you have two small children, hopefully you have some support with the kids, mommies need lots of rest and tender loving care.......happy mothers day if I forget when the time comes.
I am losing my internet connection as I have to move today and tomorrow and do not own a computer of my own.
Love to a lovely,
Linda Marie
