SO why does this shitty antihistamine give such a powerful rush - intensity can be compared to benzo or racemic methamphetamine - you just need to crush 3-4 50 mg pills add water shake a bit and filter it out. Though it burns veins. I don't understand why it does that too. It can be mixed with a shot of methadone or heroin to strongly increase your rush and high. Some dealers in US do it and users who don't know this burn out their veins VERY FAST . keep in mind I used heroin for ~4 years and never ever heroin alone burned out my vein.
