last night I took a fair amount of very pure powder rapped in a rizla and before that he'd had not quite so much but dabbed on the gums. He took the first dose at 4PM and the second at about 1AM. He had something like 0.05g the second time. The almost immediate effect (after ingestion) wasnt too good. He started to feel quite shaky which continued for a few hours. Whenever he got up he felt weak and sometimes got a massive headrush Basically he got irregular heartbeat for hours - its 09.20AM now and although its calmed quite a bit from how it was before. Swim checked his pulse rate and found it to be over 120-30bpm although it was really hard to count as it kept skipping beats. He also felt a huge tingly sensation throughout the whole of his body a bit like pins and needles for quite a while. I dont know if it was 1/2 hour or an hour. For the most part its calmed down now but its still going too fast and his chest hurts slightly, though that may be because he keeps having to take deep breaths to try and minimize the irregular heartbeat (or palpitations? He could notice/feel his heart giving a huge beat if he forgot to breathe). I was going to try Atenolol as i have access to that but im not sure on drug-interactions. Other than that i can only get OTC medicines - is there anything that would help? Thanks in advance Well, even though no-one seems the least bit interested, i'll post a follow up anyway. I found a nice kava extract he hadnt tried yet to be quite effective and very calming to the heart, although his heart rate wasnt as fast as it was (120-30, compared to 66 normal) it did slow it down to a much easier speed very close to normal. The after effect of the whole experience was extreme fatigue for the whole of that and the next day. Massive headrushes when he moved about making him feel faint enough to make him lie down on the floor, almost blacking out etc. He did also not want to eat for the period of time. He reccomends taking Periactin as an appetite stimulant, although it makes you feel drowsy.
