Caffeine?

So I've heard that you should limit caffeine when you are ttc. I'm trying to cut back to one cup of coffee per day but it's such a struggle. On top of that I start work at a hospital next week where I'm gonna need energy to get through the work day and I get so sluggish in the afternoon. Has anyone had issues conceiving because of caffeine? Any tips? #caffeineaddict #thestruggleisreal 😬
