Sheep Drench-Bad reaction

Bad reaction to Ivermectin Sheep Oral drench. I just took my first dose of Ivermectin of the animal meds (sheep drench) and I even took a slightly lesser amt than the 16ml I was suppose to, I only took 10ml (Active constitution Ivermectin: 0.8g/L). It has knocked me around so much with nausea, migrains, sore/stinging blood shot eyes, lethargy, dizzyness and slight burning in my throat when taken). I thought I read that it stated it was concentrated but now I can't locate that information. I have 5 litres of the stuff..lol and I don't think I can take it again. It does state that it is poisonous if swallowed but I presume all animal products state this...Any suggestions as I have now stuffed up taking the Ivermectin component in ICU's Albendazole & Ivermectin protocol. I can't get the horse paste as per the ingredients of the protocol unless I order from the US and that could take months to receive. I have been taking the Iver from the Dr but ran out awhile ago and now don't know what to do as taking a lesser amt could result in resistance. Would appreciate any advice,Cheers Zippedo
