During lockdown I gave up my regular can of full fat cola, not every day but most days I had a can. I went 4 months without any fizzy drinks at all. I already don't drink caffine or smoke and I've never drank alcohol. My diet is pretty good, vegetarian for 20 years, all health from scratch cooking. I expected to feel rubbish the first few days and week but I just never felt much better even after months of no drinking coke at all I felt headachy, foggy and tired. The past week I started having the odd can again and feel so much better, more alert and have more energy.
Not sure what is going on here it the coke doing something like raising my blood pressure slightly from being too low to make me feel better?
