So, I've been taking Femara since Friday - that's four nights of taking it. I take it before bedtime. So far, so good. I don't really feel any side effects. Maybe a slight headache here and there, maybe some fatigue but not any more less than what I've experienced before. Others include dizziness, nausea, sleeplessness, double vision. Maybe after it's had a chance to build up in my system, I might get more achey joints. But nothing really to report right now. Let's just hope the medication does what it needs to do in terms of turning off or slowing down the cancer growth in my lungs. They say it might take a month or two to work. I'll keep you posted!
