I've been up for almost 30 hours now, and have a pack of 32 8/500 co-codamol (256 mg codeine) i have preformed a CWE but i am now unsure if maybe my body cant take it due to lack of rest. I am 215 lb's, had a previous addiction to codeine up to doses of 400 mg's which i stopped 1 month ago. Would taking codeine cause any serious unwanted side effects whilst sleep deprived? cheers in advance.:D
