So last night after suffering from some crazy shit withdrawal symptoms of a painkiller it almost came time to call an Ambulance.nI had the fun symptoms of:-nâą Dizzynessnâą Headachesnâą Appetite Suppressionnâą NauseanHowever, it turns out that these side effects compound in to pure hell on their own accord. I felt as if I literally couldnât eat more than a few mouthfuls of food, so I hadnât ate a whole lot over the last week.
