Hi Tony , I'm with you on the taste issues still having very altered taste myself.
Strange what you say about coffee sometimes tasting sweet the very same thing happened to me I was adamant Mike had put sugar in mine by mistake . Chicken beef steak not much taste , gammon bacon salty meats much more palatable . Veggies taste pretty good specially mushrooms , sweetcorn, courgettes . Milk and eggs okay for me . Sweet stuff still craved but very disappointing . Also like I've read on here before often the first mouthful is better than subsequent ones .
Take care Di
