Q: I am not a huge fan of caffeine (aside from my morning cup of coffee) but there are times when after a long day at work it is really tough to get up for a good workout. My drug of choice here would be sugar-free Red Bull, but I am leery to start introducing something like that to my routine. What do you think - good, bad, who really gives a crap if it works for you?
A: If you can tolerate it, it’s fine. If not, don’t use it. It’s not like you are injecting heroin so I wouldn’t worry too much about it. Stimulants, especially the older you get, have a bigger price so be sure you are willing to pay it.
