Так попробуйте

var Data;var ii=0;
function go() {var data=Data;
alert("Ok!=+ii");
var row = '';
row = '<form>';

row += '<b>' + data[ii].questions + '</b><Br>';
var ss = data[ii].answers.split(',');
for (var i2 = 0; i2<ss.length; i2++) {
row += '<input type="radio" name="id_answer'+ii+'" value="' + i2 + '">' + ss[i2] + '<Br>';
}

row += '<button onclick="go(); return false;">Далее</button></form>';
$('#feeds').html(row);
ii++;
}

$(document).ready(function(){
$('form input:image').click(function() {
var drink = $('input[name=drink]:checked').val();
$.post('save_data.php', {drink: drink},
function(data){
Data = data;
if(data) {
var fieldsCount = data.length;
if(fieldsCount) {
go();
}
}
  }, "json"); 
return false;
});
});
