Does coffee help or hurt y’all?

Coffee makes me nauseas, tummy ache, and I’ll go right to sleep, I think it’s due to tummy issues :( I read somewhere that coffee blocks certain transmitters while green tea helps the transmitters make connections. I am unsure if it is the amount of caffeine in coffee or because green tea has l-theanine in return helps with cognitive function and anxiety symptoms. Tbh I can’t find the reading about blocking neurotransmitters so I don’t think that’s the case. I think it’s more dealing with my gut health.

I did some research because it has opposite affects on me and it confirmed why! Something about it helps blocks the neurotransmitters making connections so that’s why it seems like it either does half the job or not at all. I switched to green tea bc the L-theanine and caffeine work together to improve cognitive function. I also take lions mane cognition supplements!

It doesn’t help but I love drinking it regardless. Sometimes it makes me sleepy lol

I drink coffee at all times if the day and night. It's literally my favorite drink. The caffeine doesn't effect me, but I know it's still not the best thing for me to drink all day
