I haven't drunk coffee for around 3 years now and don't miss it tbh.. I miss the smell though and meeting up for coffees aspect though.
I drink tea or water now mostly. In particular, I'm keen on ginger tea with orange or lemon.
I forgot that I didn't drink caffeine the other day and drank two small bottles of Pepsi on holiday and was wondering why I was up all night! lol
My dad wasn't a coffee drinker either, he drank tea or water, as do you. His reason was the caffeine and yep, he'd look at a cup of coffee and be up all night. 😂
I think we lose tolerance to the caffeine which is probably why a couple of Pepsi's did you in.
