Now you can take this however you like but I noticed over some years that when I fly longhaul I drank tomato juice - never alcohol and never coffee or tea; not a conscious decision, just felt like it. Later, I also noticed that I never suffered from withdrawal during a flight.
2 + 2 =?
So now I'm drinking t juice at home though I never used to. Apparently, there's something in tomato which can help - what? I hear you ask. Unfortunately it doesn't have the same benficial effects on memory!
Can't say if it's helping or not but thought I'd pass it on anyway.
