Aaron,
My dad has been on the Alimta since January and seems to be doing well. He does get major fatigue about 3-4 days in and it last about 4 days. Of course, over time the fatigue is a little worse but he has not lost hair. And, yes, he had to have the B12 shots and had to take the folic acid. The amount of folic acid in a multi-vitamin was not enough they made him take a supplement. If after his May scans, the cancer is no longer stable they are moving to the Gemzar I believe on its own. Hang in there, and if anyone asks why you are taking Folic Acid.......you can always tell them you're pregnant
