thats too weak of a dose. i'd personally keep dosage above 250 at least.
i've had dozens of morning glory trips..my system is simply to put about 1 gram of them in my mouth at once, chew them into a very fine paste then swallow with soda. After repeating this a few times I follow it up with peppermints to keep the sickness down. Weed (if available) or whippets also help and compliment the trip.
