migraine
"I have tried this medication in the past and it did not work for me, but now after revisiting the drug with years of migraines of no relief I have found that it works well for me now. I tend to have extreme nausea and vomiting with my severe headaches, so I also use the nasal spay form (depending on how nauseated I am) They both work well if taken early in the migraine. I did however have severe reaction the first 2-3 times taking it (nausea, vomiting, abdominal upset) but I forced myself to take it again. Now my experience is "head tightening" which I see can be common with this drug and after about 15  minutes of this, I feel a "loosening" and finally relief. I have not experienced any other symptoms with tablet form."
