There are supplements, backed by research, that practically remove all of the negative side effects of adderall. To start with, the sadness you felt on vyvanse sounds like dopamine depletion. You want to be taking l-tyrosine to make sure there’s plenty of fuel for the amphetamine to work with. ALCAR + ALA counteract the psychomotor agitation and tolerance formation. Magnesium + zinc help with muscle cramping. Selenium is neuroprotective. And of course you want to make sure you’re getting enough electrolytes (sodium + potassium) and balancing your intake, as a general rule for life, but especially if you take stimulants.
With the aforementioned supplement stack I’ve been able to go off doses as high as 60 mg of adderall per day without any significant withdrawal symptoms. It’s been a complete game changer in terms of making this medication a sustainable option for me. I will say as a caveat that things which reduce drug tolerance formation also typically attenuate some of the effects. In my case, ALCAR + ALA basically erase the potential for euphoria but don’t seem to diminish the mental benefits.
