Progesterone Question

Erica
My Dr. has me on progesterone tablets (I take 2 every evening for 10 days, unless I conceive then I will continue to take them) Anyways, this time around they are taking their toll on me I've been sleepy to the point where by lunch time I can barely keep my eyes open and I have been  grouchy and find myself snapping at my husband.  Has anyone experienced this while on progesterone?? It's never been this bad before while I was on it. PLEASE HELP!
