i have a friend with this illness. She is of child bearing age and takes thalidomide. It is working really really well for her. She is not in a relationship, and is not one to sleep around so the birth defects thing does not bother her. I used to work as a haematology nurse, where thalidomide was used for a wider range of disorders, so it feels pretty normal to me (i myself was on some tablets where you are not supposed to get pregnant (untill i got pregnant!)) However, as you have seen from previous replies, thalidomide has a very bad name, and you/she will have to be prepared for reactions like the above when people don't really understand that the symptoms of an illness can be so bad that you want to try, or follow your doctors recommendations.
I also take steroids and will never forget my sister saying something to me like "steroids are so bad and have so many side effects that I would never ever take them". I was so upset because at the time they were the only medication that allowed me to function, and she was in the lucky position of not having to choose because she was well! people can say things without thinking sometimes!
