What kind are you taking? I took Prometrium last cycle and it did make me sleep well. Are you taking it at night? I had the best sleeps ever while taking it, but it did make me feel like I needed a bit of a nap mid-day as well. I swear I gained like 10 pounds as well. LOL! I am only laughing because I am off it right now, and I am back to feeling like my old self, but next cycle we are TTC again (just took Christmas off). Then, I too will be feeling like shite. Guess we can just hope that it is all for a good reason, and then it will be worth it in the end.
