…and SIS Go comes in 500g bottles too. A tablet ‘preparation’ will not fit much in the way of energy as the dextrose has a certain volume/weight: think of a 50g dose of SIS Go as being like a crushed-up golf-ball-sized/shaped tablet, and imagine how much fewer calories a little fizzy table will fit in. Diluted fruit juice plus nuun tablets might be a good alternative (I quite like it) but if it was me I would go for a few 40g sachets or 500g of a drink I knew I got on well with.
btw sis go is also excellent for hangovers 😀
