Get some Imodium/loperamide - 20mg or so. It helps more than you'd expect.
Heroin is a tough one. The people who can take it or leave it, well I don't think they have really ever felt good h do its magic. They can only chip because they have weak h or aren't doing a lot or with an effective ROA. But for us who have felt a good dose of h, we're gonna want that each time we chip, right? The problem is that it's easy enough to take time off after mediocre h and no tolerance, but even a day with good h will have us obsessing for days and days, phantom WD symptoms, etc. To effectively chip the highs can't be all that good, but as people obsessed with h, we only want the best.
I really thought about it today too. A lot of my clean friends relapsed this week and it is getting to me. Tax return should be here tomorrow. I keep thinking about all of the pain and the shell of a man it turns me into, though, and try and take it hour by hour.
It sucks, no way around that, though, but time.
