I'm prescribed 50mgs of "Vyvanse". This is what I usually do to receive more out of it. Take after a fairly small & healthy meal (or just on an empty stomach for it to kick in faster).... take 3-4 "Tums" about 10-20 minutes after ingestion and maybe a couple more a few hours later, since antacids can potentiate amphetamines. Drink plenty of fluids (8-10 glasses of water) and eat a bunch of fruit. If you wish to feel more of the stimulating effects, drink a couple caffeinated beverages through out the day, preferably green-tea or yerba-mate over coffee... There's hardly even a crash/comedown so just drink some herbal tea, like chamomile or kava-kava, or at the most just take a small dose of a benzo/anti-histamine/or any other CNS depressant, maybe a glass of wine or a beer or two. I take 2-4 mgs of clonazepam (although I have a pretty high tolerance).
