So i take Adderall and it really helps, but I can't take the doses that would be optimal for me due to the tachycardia that I get from Adderall. So I'm thinking of asking for a prescription of either beta blockers or ACE inhibitors. My blood pressure is fine (105/70)ish. Some studies have shown that ACE inhibitors can reduce heart rate at the high end, so I'm partial to them, but i'm not sure if my psychiatrist would be convinced (plus they might reduce my blood pressure to low levels). Beta blockers are more convincing (as they're more well-tested), although they increase blood glucose levels (and any increase in blood glucose above 85 mg/dl is associated with increased mortality). In the end, I'm considering biting the bullet and taking beta blockers for a couple of years, but I'd like to think of other solutions.
but wikipedia says this:
Beta blockers must not be used in the treatment of cocaine, amphetamine, or other alpha adrenergic stimulant overdose. The blockade of only beta receptors increases hypertension, reduces coronary blood flow, left ventricular function, and cardiac output and tissue perfusion by means of leaving the alpha adrenergic system stimulation unopposed.
So I'm really somewhat concerned. My heart is supposedly normal but I got two false positives, and the presence of false positives may still be more potentially troublesome than the presence of no false positives. I really don't want to have cardiac enlargement or sudden death, but most of the time, I'm academically nonfunctional without stimulants. But chronic tachycardia might cause this too.
Right now I'm thinking of Carvedilol (since it doens't seem to affect blood glucose) or an ACE inhibitor. I fully know that Adderall is somewhat neurotoxic, but I really need it for now (I might switch to ritalin + deprenyl later).
