Morning glory is a sacrament, man. You don't just take it to "trip balls" or "get hallucinations." Its a serious, somewhat surly botanical that demands respect and attention. If you eat 500 heavenly blue morning glory seeds,
trust me you will trip very hard -- but part in parcel of that experience is nausea, cramping (sometimes so severe it feels like borderline ergotism), and a heavy sedation. It's also not very visual, not like LSD at least, morning glory visuals tend to be much more organic in nature and emphasize the blue and orange ranges in the visual spectrum. It can be absolutely divine, but you can't go into it with expectations -- you really need to just eat a large amount of seeds (grind them up and eat them, no extractions) and lay down with headphones and eye-covers on. Let the feeling grow, accept the nausea and cramping for what they are, and go with the flow. Don't expect an LSD-like trip because you won't get one.
Morning glory is tough, mindfucking, and paradoxically sometimes even very subtle. Develop a relationship with the plant; admire its beauty, read about its history and botany, and maybe even try to cultivate some -- then maybe it will treat you better.
Most importantly, though, I think you just didn't eat enough seeds.
