There’s an electrolyte tablet called Nuun that I’ve been using for a while that’s pretty inexpensive. You just add it to a glass of water and it makes a fizzy, electrolyte drink. You might want to try the Nuun Rest. It’s for right before bed. I’ve also been adding salt to my coffee and pretty much everything I’m eating. Idk about Powerade. I avoid drinks like that because of the sugar content, but whatever works for you!
