Caffeine

I'm starting my stim meds when I start my next cycle, so within the next 2 weeks. I'm curious if anyone has any info about caffeine intake during your cycle. I've been doing a low carb diet and usually only have a cup of coffee for breakfast and a sugar free soda with lunch. Other than that I drink water all day. Do I need to cut caffeine completely when I start meds? Will it have an effect on egg quality? If all goes according to plan we will do the egg retrieval the first week of October. I just want to make sure I'm doing everything I can!
