A couple of nights ago,I decided to take some dextromethorphan ( DXM, cough surup)and diphenhydramine (sleeping pills, benadryl). I have tried this combination in the past and it gave me a crazy, wild trip, but i experienced no ill effects. I first took 300mg DXM and 250mg of diphenhydramine. About an hour later, after some crazy visuals, I took 100mg more diphenhydramine but was out of cough surup with only DXM active ingredient. I decided to take 4 Robotussin cough and cold pills(per pill: 10 mg dextromethorphan, 200mg guaifenesin, 30mg pseudoephedrine) to try and get a bit more DXM. I checked online beforehand and saw that 800mg guaifenesin and 120mg pseudoephedrine were not a high enough dose to cause problems. I soon started to have extreme anxiety and difficulty breathing. My heart rate had doubled to that of what it was before ( DXM increases the heart rate). I went in and out of waves of extreme discomfort and dread. I soon became very drowsy and my arms and legs went numb. I managed to keep myself calm and awake but it was a very scary experience thinking I was going to die for 2 hours straight before things calmed down. I am curious to know why this happened. Was this a bad mixture between pseudoephedrine and the dextromethorphan. I know pseudoeohedrine constricts the blood vessels in the lungs and mucus membranes. Maybe my blood pressure got too high?
