Your husband sounds like he is going through the exact same thing as my husband Terry. He's only made it through 5 so far and the last one made him sick as a dog. He can't do every 2 weeks. He does it every 3 weeks but this time I believe it will be 4 weeks because he still isn't fully recovered. Just starting to eat better and he is just to thin and weak. He took some of the treatments pretty well. he has a colostomy and seems to be having alot of trouble with blockage or something. He's going to a gastro specialist tomorrow. he wants a recection before any more treatments and is very insistant about it. They did a scan before his last one and the tumors are shrinking so I hope he doesn't give up.
