It makes getting through work days when in mild withdrawal much easier, but I typically use lower doses than that to avoid an awful comedown. Usually I do this when I know I'll be able to cop after work so the crash is usually not something I'm too concerned about. I especially like the amps for when I'm making the transition to buprenorphine after a period of using heroin exclusively for a couple weeks to a month. Makes the switch so much better for me.
