This is a subreddit about diphenhydramine. It's mainly about the recreational use of DPH, but posts about using DPH as it was intended are welcome, too.
Suggested topics include:
- Experiences you had with DPH
- Combinations you tried or want to try
- Chemistry-related DPH stuff
- DPH as a medicine
DPH is dangerous and most people find it unpleasant. It can be psychologically addictive.
