Bah only take DXM alone with no other active ingredients, you never know what side-effects may occur along with DXM being with another active ingredient.. DXM isnt all that safe either. I've done it 3-5 times... and still hope to do some.. goto walgreens...rite aid.. longs drugs... get robitussin extra strength geltabs.. theyre cheap.. easy... and dont taste like shit.. and doesnt leave your breath smelling like cough medicine.
