I have been on chemo 3 times and currently on Folfox with two to go. I have in the past, and currently have experienced Nausea, throwing up, unable to eat and sometimes even difficulty drinking anything. I have had to force myself all the time to eat and drink and I do it. I'm not saying that your husband can do the same thing, but this is not an abnormal situation for you. If it continues all the time and he continues to loose weight, the Doctor can give him someting to help. I know it's tough but I have had to fight the same side effects 3 times now. I'm winning this battle after three years. Hang in there and keep the faith. We all pray for each on this post, and, because many of us have faced the same thing we can sympathize.
