Hi Sueg,
I think that 5 good days in a row is really good. It's a good start.
Have you been overdoing it during those good days? That often happens: you feel happy and so relieved that you are better and then you start doing so many things... too many things..., maybe not watching your diet so meticulously? Too much physical effort?
Sadly, no one can predict how long treatment will take, that is one of the things that make it so hard. But 5 good days after 4 months of treatment is not bad at all!
Keep up the good work!
