Clomid

I am on my first cycle of Clomid 50mg and I'm on CD19.. I feel exhausted. All. Of. The. Time. I'm also a nicu nurse and my job has been extremely stressful lately, but I just feel like I can't get enough sleep. I have been really making an effort and I've been getting to the gym 3 times per week but even that isn't lifting my energy level! Did anyone else on clomid feel like this??
