Day 22. Tiredness 2 hours after waking up? Experiences?

So I quit caffeine 22 days ago. I'm argentinian and I've been a heavy yerba mate drinker for around 8 years which in my case would give me around 400 mg caffeine per day. I dropped it because of unstable energy, constant anxiety and midday crashes. The thing is I've been feeling very tired over these past weeks, being the worst 2 hours after waking up.

I wake up, I start working and after I hit the first hour and a half, I get HUGE sleepiness which makes me take a nap. It is so frustrating needing to nap 2 hours after waking up because it is supossed to be the time of the day when I have peak energy. However, noons improved, more stable energy after lunch and the anxiety is much lower, but being so dead in the mornings is just unbearable.

Did anyone have a similar experience? Did it get better over time? Any advice on how to get some energy when this happens so I avoid napping so early in the day?
