Hi Amy,
As you can see from the above posts, everyone has a different story. I would suggest that you support your husband's attempt to drive both ways each day. It doesn't sound like you'd be able to convince him otherwise at this point.

After a couple weeks of treatment, it should become very clear whether this is going to work or not. I would suggest checking with the hospital to see if they have an arrangement for out of town patients or recommend any hotels/motels that offer discounted rates for patients.

If there are such places, contact them now to see how much notice they would require to accommodate you and your husband and make a back up plan. My sense is that ultimately, it will depend on how severe the side effects are and as you can see, everyone reacts differently to the radiation treatments. I'm also curious why the treatments are four days a week. From what I've read on the OCF site, it seems like five days/week for 6-7 weeks is the norm. Best of luck for a successful treatment. - Sheldon
