Yes, tbh I thought it tasted rather unpleasant at first, and still do from time to time (my relationship to food is weird and easily affected/coloured by connotations) hence trying to drink it fast. I think part of the problem is that if you try and drink it fast (especially in a hurried this-is-unpleasant-lets-get-it-down-quickly sort of way) you end up gulping down a lot of air as well. I now quite enjoy the taste (it’s picked up ‘healthy’, ‘fresh’, ‘rejuvenating’ connotations in my mind).
