I almost always found oral harmalas and vaped dmt to be too intense on the come up. I usually got so scared in the first 5 seconds that I could not really enjoy much of the rest of the trip. The times that I did get over the initial shock or feeling that I must have broken my brain, it was amazing. For me vaping dmt on oral harmalas can last almost as long as pharma - that's because pharma for me lasts only 1 hour...

anyway, I can totally see where you are coming from with being rattled by it.

better luck next time

cheers
