Well pro b has worked for me , along with the propanamol? And oxybutin? I've finally found my answer , only problem is it makes your mouth that dry you literally can't even eat without having water at he same time! I had to receive the heimlick manoeuvre a week ago as I started choking , PROPER choking on a pastie , I was 2 seconds away from passing out! So word of warning , anyone using it , please be careful when eating!:thumbup:
