Lately I've been vaping my harmalas followed by vaping DMT, and that seems to work the best for me. I've noticed that when I take the harmalas sublingually that I too was having much frustration "getting through the front door". I really didn't know what could be going wrong. I'm not sure why, but between our stories, it seems like there might be a complicating dimension to sublingual harmalas for some that we are unaware of. You have your enhanced leaf, but do you have any DMT freebase laying around? If so I would try that. If not, try vaping your harmalas next time (you'll need a bit less than with sublingual) and then vape your DMT/enhanced leaf/whatever.
