I must stop drinking caffeinated drinks. I stopped completely for 2 weeks and I feel fine. My muscle twitch was completely gone. But I’ve just started drinking decaffeinated tea again these two days and my muscles started twitching again. My mood also becomes negative. From now on, I must avoid caffeine at all cost. All it does is destroy my health. It can give me a few hours of energy but after that I feel like a total wreck. I MUST STOP DRINKING CAFFEINE!
