I was prescribed tramadol some years ago. Didn’t work at all and made me very itchy and groggy.
@ejs - tried your recommendation. Tried to set upstream interleaving = off in AA’s clueless.aa.net.uk server. Lit up with a bright red error message and told me to get lost because the interleave=off was incompatible with the interleaving depth value chosen. However I can’t choose any other value for the interleaving depth so the experiment failed. Literally ‘computer says no’.
