Hi: I have never taken VSL#3, although there have been many posts here from those who have taken it and some good and some so-so reviews of it.
I know that probiotics do not work for everyone, but I can only pass on my results. I am still on them and will probably be on Dr.Swanson's forever. They work for me. I am, however, trying get off of Lialda. It has helped me, but it is very expensive. I am on medicare and social security and my yearly pharmaceutical "allowance" will be used up by June because of Lialda (all of my other meds are generic) so to go into the donut hole in June is not something I want to do. My gastro doctor will probably prescribe Sulfasalazine. It is generic and is highly recommended for ulcerative colitis. It can cause kidney problems so that has to be monitored regularly.
I try to watch my diet, and sometimes I'm successful and other times I "give in". But things like salad and fresh veggies and fruit are a no no. I can say tho that I haven't had a severe flare (knock on wood! Hope I don't regret saying that now!), for quite awhile. Spring is around the corner so that is usually "flare time".
I wish I could give you more advice, but sometimes this is an individual thing...what works for some doesn't work for others.
Also, a friend of mine with Crohns was advised by her doctor to try FloraStor probiotics. They're over the counter. Most doctors do recommend them. I don't think they're a long term thing tho like Dr. Swanson's are. But they worked very well for her during her last flare.
Let's keep in touch so we can compare notes. That's what this site is all about. It's great. Look forward to hearing from you.
