its best to take robo with only dxm in it, get the robotussin cough gels at walmart or safeway, 20 to a bottle 15mg each. take them all you will feel really drunk and have some minor CEVs. or at least i did, i weigh about 150. if you can control yourself drunk around parents you should be good, just try not to walk infront of them, i got bad robo walk and lots of stumbling.
