Experiences with Dex and/or Adderall

[getonline]

I take upwards of 60mgs of dex within 1/2 hour (40 by ingestion, 20 by snorting) two times a day. I get no euphoria out of it, my hunger was only suppressed for a week, and I find myself yawning and feel I can easily go to sleep!


The only real evidence of the drug in my system is dry mouth, and my heartbeat becomes fast and irregular when I stand up after sitting a while (is that causing a rise or drop in bloodpressure?).


I've read posts here about people getting euphoric and energetic off of dex. Does anyone else find themselves immune (or tolerant) to the recreational benefits of dex/adderall?
