Lazy bowels from antidepressants

This is a problem with lots of people including me and I always am embarassed talking about it with my doctor even thiugh I shouldn’t be but I was just wondering if there is a natural laxative I could take like overnight that would just make me more regular? It’s not as much That I’m constipated it’s just that I can go days where I don’t even need to, I’m very nervous of mixing other medications with my venlafaxine and I can’t quite get a straight answer on google if senakot and others mix with it so I just wanted a personal opinion/ experience !

Thanks in advance :)
