In addition to the above u should also have modified ur diet and lifestyle....if u smoke u should stop...try and relax as stress can trigger flares and avoid foods that will make u feel worse...greasy, spicy, acidic foods as well as carbonated drinks and caffeine.....
As for the probiotics, to get the same from yogurt u would need to eat 3 a day, not just one in the morning....it is a help, but may not be enuff.
Do u lay on ur side?...if so try ur left...and lower the bed if ur spine is being affected by the incline...not sure how or why that is an issue...but u may have something else going on there.
