There are others like vasodilators that relax blood vessels and lower it through less constriction of vessel walls.
That sounds really nice. Isn't this what viagra does?
That is ***precisely*** what viagra does. The original design goal for Viagra was as a new vasodilator. This one for whatever reason - involved the male genitalia more specifically than anything else
Now that the thread has devolved and gone way OT - Lets describe some of the lesser-known uses for OTC medication:
1. Pseudo-ephedrine or ephedrine is essentially cheap fake speed. Ensure you take "immediate release" and not "extended release", and get about 100mg in you all at once (usually 3-4 pills). You'll have a couple hours of zing in your step. Keep taking it and get up to over 500mg in a 24 hour day (not all at once good lord no!) and you are likely to be a real asshole to everyone you meet.
2. Dextromethorphan Hydrobromide is the "cough syrup" dependency main drug. If you've ever heard of someone addicted to cough syrup, this is the substance. Not "nyquil". I really don't know how nyquil got the reputation for being knock out stuff - it only has 30% alcohol, and benadryl that is likely to make you woozy.
Take 150mg-300mg of DXM all at once to get a "level 1" or "body" high. You feel kinda neat and everything seems fairly significant. Its also hard to finish fapping.
Take 350-600mg of DXM all at once to get a "level 2" or "mind" high. You think you are a reptile and it is exceedingly difficult to perform basic tasks. Do Not Drive. Walking across the living room is a serious affair, every step is awesome and inspiring.
Take 600mg-1000mg of DXM all at once to achieve the "sage" or "mystic" level. You actually become a reptile here.
Beyond 1000mg I've not personally tried, but I hear there are some vivid hallucinations.
DXM can be habit forming and has been linked to "Olney's Lesions" in the brain. Essentially overuse will melt holes into your mind.
Diphenhydramine (benadryl or dramamine) is known beyond causing drowsiness as a serious mind-altering substance. I've never gotten beyond the first hurdle though. You are supposed to take a deliberate overdose, like 8x 25mg, along with caffeine or cocaine or speed or something. You are supposed to lose touch with reality. Like you can't tell what is real and what is not anymore. Its supposed to be like living in a painting for some. Every single time I tried this I fell immediately to sleep.
