How did you...

How did you solve the problem of constipation without meds? I feel like I have to use the restroom then as soon as I get up to go I can’t. And the times I do, it’s minimal and I still feel like I have to go. Any suggestions? ( Keep in mind that its summer vacation and I haven’t been getting up and active moving around like I would be going to class... could that be the reason? Not moving around a lot?) However I do drink quite a bit of water but i also drink soda and such. if you have any suggestions that would be great thanks!
