Scientifically, its very unlikely to have been the Stella. Statiscially speaking its much more likely there were impurities or additives in the crisps, the scratchings or the nuts u also had during the evening. If you were in the pub, second hand smoke, perfume, aftershave, sweat or the psot-traumatic stress of a female rejection is more likely to blame for your currenct condition. If u were at home, conventional TVs give off powerful radiation which can affect you the next day. Chances are Stella is a faithful (well, -ish) mistress and other factors are leading you to falsely accuse her.
