I didn't see the previous thread. Was the diet soda caffeinated? And did you actually give up caffeine and aspartame at the same time?

I drank Coke zero, which has both caffeine and aspartame. So, it probably is a result of giving up both, I would guess that helped with me feeling better.

The last time I tried to cut out diet soda, I couldn't get past the lack of caffeine and had horrific headaches. This time, I was feeling so poorly, I don't think caffeine withdraw could compete with the lethargy and pain I was feeling.

And, I'm not going to try to prove a causal relationship by reintroducing one or the other, since I'm feeling too good right now
