No. Just no. This is rather like saying 'Lets kill our liver with Tylenol today!'
In many states Robitussin is kept behind the counter at any pharmacy, due to people taking it for the so called 'high'.
We know that opioids do not help CH.
The 'quote' from Clusterheadaches does not produce a return if clicked on and was from 2003. I am fairly sure that you could find many totally unsuitable ideas on many boards if you care to invest the time to hunt for such posts. If this was valid and valuable information, after 17 years, there would be current posts reflecting the success of doing this.
This is bad advice. I highly doubt that members are looking for a new way to get high. What they are looking for is pain relief. Not a cheap high that might prove deadly.
fillzeros - Did you take this for CH? Cut and paste quotes are fine, but not as a stand alone trying to prove the efficacy of a destructive treatment. Dredging up old posts is ok to support your point. However, your point seems to be to get high, not get pain free. It works for you? In looking back over your posts, I do not find one which states that you have CH and have used Robitussin to conquer CH. Just this one which does not state that it made you pain free, but that it made you high.
