Hello
So im addicted to caffeine and i usually take it in form of guarana extract tablets standarised for caffeine(so its 500mg of guarana with 110mg of caffeine) or drinks with caffeine but not coffee since it makes me sleepy.
Caffeine makes me often anxious and causes mood swings 5 minutes after taking to like 3-4 hours abut after that time i feel nice mood and energy boost without those issues(usally at 10pm). I tried dozens of different things(legal ofc - supplements and nootropics) that should boost energy but they never worked properly, or worked but lost its effects because of tolerance like phenylpiracetam.
I have slight histamine intolerance but caffeine itself and other methylxanthines are mast cell stabilizers so im not sure that may be the cause(but i know caffeine reduce DAO though).
I tried different caffeine sources like yerba mate, ilex guyausa, yerba extract, kola nuts, pure guaran powder but in every case anxiety is present. Stacking it with magnsimum citrate and 1-2 grams sometimes remove part of caffeine side effects but this stack cause diarrhea and is unpredictable. Stacking it with l-ornithine completely removed energy boost so i also dont take it anymore.
Any dose of l-theanine make me sleepy and spaced out even if stacked with caffeine so please dont suggest it.
I tried expensive substitute for caffeine - theacrine but it only made me sleepy and unmotivated.
Plase help me with this issue as im struggling with it since like 3 years and it makes me unproductive and miserable. Also when i dont take any source of caffeine i sometimes feel pretty good during the day but im always exhausted at late afternoon so thats why cutting off caffeine and stopping to take anything is out of the question.
