You guys are silly. I much prefer a LONG extended release stim high to a shorter high that peaks then comes down.
I used to get vyvanse and would get high for 24hrs, nice and steady comedown the entire next day (which wasn't unpleasant), sleep the third. I'd typically take 150mg-250mg with no tolerance... I only did them rarely. I've seen doses other people take and lots of people were taking less than I was with a tolerance, if I remember correctly. I'd get the 50mg capsules and typically take 3-4. I did 5 once but it felt very unhealthy and rough on my body. Was getting random light twinges of sharp pain in my body at random intervals/places. My right testicle kept a consistent pattern of twinging with a similar pain in random intervals up through the 3rd day. The high was good though. Gosh those were enjoyable, but amps are so stressful on the body I don't care to take them more than once in a while. My body is physically weak enough as it is, I can't handle taking it more often than that.
If you have enough extened release ones to get a long consistent high I'd recommend eating them. Though be careful with your dosages, if you don't have experience with it start at a safe dose and work your way up to a decent high. I'd imagine it's easy to take too much to compensate for the extended release and get too high or OD. Whatever you do, be safe.
