In the past year or so I have had terrible headaches and redness of the skin when drinking wines (usually the supermarket bought variety!) one glass could be enough for me to wake up in the middle of the night feeling like I’d been hit over the head with a mallet. I thought there’s no harm in giving something a try. So, last night I put it to the test, and just to be sure, had a fair few glasses of red wine! (I have most side effects with red) each time I refilled I sprayed my glass about 4 times beforehand. It really is odourless and tasteless. Instantly I noticed a difference in my skin and neck. No redness or hot flushes. During the night I did wake up, but noted - no headache! And the next morning, no side effects at all. This will be a game changer for me over the festive period. (Though not a daily habit!) my only reservation would be using it at pubs or restaurants discreetly without anyone thinking you’re spiking a drink. The silver bullet type packaging, although sleek and pretty, does give espionage vibes! Overall though, can’t go wrong if like me, you’ve suffered heavily when trying to enjoy a glass of wine.
