Sounds like you might be expecting to get more out of your meds than they're able to give. So your going to be disapointed when there's no coke/E type rush. I think a couple people already mentioned crushing and/or disolving the beads to get an IR affect. That should help with the sleeplisness you experienced before. Keep in mind not everyone gets the same results from amps. I think the rush you describe comes from methamp.
