Val,
Hi! I don't have any experience with Alimta, but I do want to tell you that my mom has had several bad days in the past few months which led me to believe she must be getting worse. In reality, they were just bumps in the road. I think it's very difficult for those of us looking on to accept that the patient is going to have rough days, especially with chemo and radiation.
I hope your mom starts to feel better soon. I am so glad you get to go spend time with her in the not too distant future.
Sending nothing but prayers and good wishes your way.
