Nodding might be a bit much to expect from codeine if you've any sort of opiate tolerance/experience, ol' mate.
From a former dope head, i would suggest a teaspoon or so of ground black seed (also called kalonji - often found in middle eastern stores) - or the pure oil if you can find it - and dose it shortly before a lowish dose of pst.
I cant emphasise the "dont dose pst as you normally would - black seed potentiates like a mothefucker", trust me on this one)
Play safe and work your way up.
Imo tramadol is pretty shit (expect in combos - but there are too many complications) and seizures arent fun.
