Yeah, I used to take Dexedrine and sometimes Adderall or Vyvanse, mostly for recreational effects, and I did always combine it with caffeine. Sometimes I enjoyed the experience and other times I got anxious and didn't. It's not a very smart thing to do, but I don't think you are risking death by taking moderate dose Dexedrine/Adderal with a little caffeine, but I don't plan on taking any amphetamines in the near future.
Doesn't caffeine also reduce GABA? What does it mean to "increase glutamate signalling"? And what do you think the interplay, chemically speaking, would be between the high doses of caffeine and Klonopin I used to take?
I mean NOW I am off caffeine (I hope it lasts) and have reduced my Klonopin and I feel better, but my old psychiatrist used to say that drinking all that caffeine counteracted the anxiety reducing effects of Klonopin. Of course he was correct, and had I never gotten into drinking so much coffee I probably never would have needed Klonopin. My guess is that Klonopin increases GABA and caffeine decreases it, so they are just counteracting eachother, but it was always necessary for me to feel awake on larger doses of Klonopin.
To be honest, most recreational or medical users of amphetamine also co-ingest caffeine, either through cutting agents or coffee. yes, of course in small amounts caffeine shouldn’t make amphetamine massively more dangerous, but it will likely modify its effects especially when it comes to cognitive performance. just out of interest, have you ever tried amphetamine without any caffeine? not suggesting you try amphetamine again recreationally, but if you ever do consider trying an amphetamine type stimulant at low doses, do it when you have no caffeine or related compounds in your system and you might have a much better experience.
In regards to caffeine interacting with Clonopin, it’s not a direct interaction because they work on different receptors, but the overall effect is still likely to be diminished effectiveness of Clonopin when caffeine is in your system. Clonopin is a benzodiazepine that enhances GABAA receptor signalling and just generally calms most areas of the brain including the anxiety centres like the amygdala but also important memory centres like the hippocampus and other brain regions needed for wakefulness/consciousness and emotions. this is because the GABA System branches out into every brain region and directly controls their activity by producing inhibitory signals. this is why benzodiazepines are good at treating anxiety, but also why they produce so many cognitive side-effects and motivational deficits.
On the other hand, the adenosine system, whilst still having huge influence across the brain, has more nuanced, complex and specific actions and is more concentrated in certain brain regions. adenosine via A1 receptors produces an antianxiety/antistress affect, but unlike GAVAA receptors, activating it can also produce an antidepressant affect. when no caffeine or xanthines are in your body, natural adenosine puts the brake on the anxiety centres of the brain, without negatively affecting memory or cognition. A buildup of adenosine is responsible for the natural, desired and sometimes pleasant groggy/lethargic feeling which makes you drop off to sleep after a long day of exhausting work.
In regards to decreasing GABA and increasing glutamate, these are some of the proposed mechanisms of modafinil. Note that if these things do occur, they would be very minor changes and only in certain brain regions. as I’ve mentioned previously, GABA is the main inhibitory neurotransmitter in the CNS. A small Brain region selective decrease in its activity can enhance neuronal excitability and functions related to that brain region. meanwhile, a brain region specific increase in glutamate(Main excitatory neurotransmitter of the brain) has pretty much the same effects.
Going back to caffeine, by blocking adenosine, it is able to make stimulant drugs or cognitive enhancers like modafinil excessively stimulating and tipps the balance of neuronal activity towards too much excitability which causes stress, anxiety, disturbed cognition/concentration etc. likewise, caffeine would probably have a stronger affect in the brain’s anxiety centres since they have a very high concentration of adenosine receptors or receive strong inputs from adenosine releasing neurons. this means that in the case of Clonopin, caffeine won’t directly block its affects, but it could definitely make it less efficient by removing one of the normal breaks on anxiety (adenosine).
