Wow! that was excruciatingly hard to figure out! 2 seconds on google rendered me with the maximum daily dose of ibuprofen is 3.2 grams. which equals 12.8 pills. or call it 13.. and codeine makes you itchy and flushed as hell so before you dose, 30-45minutes before. take a normal dose of any antihistamine. and previous poster said you would feel a buzz of 3-4 i highly dought that.. ive given friends of mine who have never used an opie ever about 200-250mg of codeine. one even 400mg. none of these were overwhelming or too strong because it is a very weak opiate. but yeah you cant take that many without going over 3.2g of ibu so the most u can take is about 13 pills which equates to around 156mg. I doubt you will feel that much at all maybe a tiny tiny bit of euphoria and maybe some warm, "flushing" feeling that codeine gives. and maybe some itching.. or just trade it to someone who thinks codeine is amazing because of all the hype that comes hand in hand with it now, for some vicodin or percs or whatever.. have fun and be safe, and use google and the bluelight search engine! or i forgot, if u do a CWE (COLD WATER EXTRACTION) on a whole box that should be a good enough dose if you have no tolerence and its only 288mg of codeine if you did it perfectly otherwise itll be lower. and it definitly wont kill you but its around the dose i recommend if you want to get "High"
