Yes, I second what Rach said about Clomid. Femara is VERY expensive, so call around. I get mine from an apothecary (Avella) that mixes it themselves and it's only $12/mo. It was worth the research on that one! I think it was Walgreen's that wanted to charge over $100 for it. Lol-- yeah, right!
For me, Clomid was pretty much a nightmare. I've always reacted badly to birth control pills, so it's clear that I'm sensitive to hormones. The biggest side effect for me was total emotional unpredictability. I also got a bit paranoid and accused Hubby of some random and hurtful things. It was a disaster for us. (And, yes, this was on the lowest dose.)
Clomid also can thin out your uterine lining. It didn't for me, but I've read some women have that issue. As far as drying you out, I think they both can, but I was much drier on Clomid.
Femara doesn't cause the same hormonal response because it is actually an aromatase inhibitor, meaning it blocks production of estrogen. This makes your body go into overdrive to stimulate follicles. Clomid fools the brain into thinking it's not making estrogen (although it is) and it reacts the same way.
Finally, Femara's half life is really short. It's out of your system after about a day. Clomid's half life is much longer, so side effects can last several days after stopping taking it.
