anything with carbs- potatoes, pasta etc will keep u feeling fuller longer and give you ‘fuel’. also drink PLENTY of water, not all at once at the seuda, but keep a waterbottle nearby the whole day today (erev) and take sips every few minutes, it builds up ur body’s hydration slowly and keeps u hydrated for longer as opposed to just downing a waterbottle a few minutes before the fast. some ppl like powerade before a fast, but i think the benefits of powerade are more considerable if you drink it after the fast, cuz it replenishes you from dehydration
stay cool and have an easy and meaningful fast!
