dear marie sorry to hear of your problem,(yes i also had an x that was this monster alcoholic besides a junkie)....never mind that.
I am a homeopath and sometimes use herbs for ailments ,i found that the Kudzu vine that growns in japan and tennesee usa deals with this problem verry well.
Go to google search; kudzu vine info.
Dont think it will grow in belgium it is way too cold there,I'm having a hard time growing it here........good luck
