The longest I was on IVs was 7 weeks. I did 4 weeks on one triple cocktail, then 3 weeks on another. In the end I never felt better and settled into what I thought was a new "baseline" for a whole year. I kinda felt the docs gave up, but seeing as the IVs weren't working at the time, it's probably good I was off them anyway, to reduce other bodily damage. I've since increased my "baseline" a smidge, this is 2.5 years later and I feel much better. I've also been on several quicker rounds (15-28 days) of IVs since then that have actually worked. The only bug I've ever cultured is PA.
