You sure the 4 oz. is only 237mg?? It looks like alot more than the pills in the container if they were liquid. The pills r 15mg and the vicks is 30. There must b more mg in the bottle.
CanaBliss Reviewed by CanaBliss on . Finally My Day Has Come That I try DXM. Today I went to Target and kinda snitched a bottle of 20 Robotussin gelcaps and a 4 Oz. Vicks 44 Cough Relief. Yes, they only contain Dextromethorphan. I have 3 questions..... 1. How many mg's is in a 4 oz. bottle?? 2. How long should it last, I am taking the coughgels which say they control cough up to 8 hours long. 3. Is 300 mg enuff for a first timer?? Any experiences with 300 mg? I weigh 135. I know theres ALOT of posts about DXM and I'm not a DXM head (no pun Rating: 5
