Every time you drink something with caffeine like coffee, or alcohol you're activating the body's same fight or flight response. But instead of making cortisol and releasing adrenaline so the body can deal with a short term stressor like a tiger chasing you, the adrenals are doing so in response to your caffeine, or alcohol consumption exactly the same.
Repeated doses of caffeine over a single day for example result in markedly increased cortisol levels, and this is independent of sex of the person or stressors they were already under.
This gives you a temp boost in energy from the cortisol but since that is making the adrenals produce the cortisol, dhea, adrenaline etc from body resources, in those that are already low on those resources it will make things worse by further depleting them pushing you closer to adrenal exhaustion.
Cortisol prevents cells from losing sodium and accelerates the rate of potassium excretion. A high calcium to potassium if you dont compensate will slow the thyroid down, causing weight gain among other things from the constant cortisol from the stressors.
You could try instead 3 oz Orange Juice, 3 oz Coconut Water (I use 365 whole food brand), 1/4 tsp Himalayan Sea Salt, 1/4 tsp Cream of Tartar (I get mine at whole food). This would give you around 500mg potassium and some sodium and small amt of other electrolytes and whole vitamin c helping to boost the adrenals more properly helping them to restore lost levels rather then depleting them like caffeine and giving some energy. I do this 2x a day around 10a and 2p usually.
While still up and functional I used Trace Elements Adrenal Complex, which would give you some cortisol without the drug issues and supporting vitamins lessening the burden on the adrenals and might help to let your resources recharge a bit then go off them. Just keep in mind this can mobilize stored metals and you may then have to deal with liver/bile flow and detox such as using pectaclear.
