I have been on Ty for 2 months now, the first month I had nausea and abd pain after the infusion..second one no problems! I do need a nap after though. I have had some pseudoexacerbation symptoms from stress while hubby was in the hospital but overall I'd have to say these have been the best two months I have had this year! Not to say I am fabulous I still have my persistent symptoms that I have always had but I haven't had any bad flares either and for me that is enough!
