Hi,
You may try IMI or Health Gate which are selling ochisicollinum?(sorry if I mistake to spell it, but too long to remeber, everytime..)
as my case, I tried that last year for flu, sometimes I felt relief but sometimes I didn't, finally I found a homeopath who sees me and my family as well.
Try homeopath if you feel you can't solve any constitutional problems.
