Ime sublingual FBed harmala doesn't have a strong taste, but manske salts do, intensely so lol. Maybe I'm a bit of an anomaly there? But thought to share my experience.
Myself, I don't find rue all that euphoric on its own. It opens a meditative headspace and pushing dosage higher makes it more psychedelic but with more discomfort, nausea, vomiting even, dizziness etc.
I suggest when you get the FB just put a tiny bit on your tongue and try it. If it is true freebase it has significantly less taste than salt form. But I love the long afterglow myself so we may have different tastes.
