I,ve been taking Verapamil for about two to three years now as a preventive and obviously it is not working or I am taking the wrong dosage (200MG) each morning. I've always had CH but for some reason this season is the worst I'd ever had ,I have oxygen (6 liters) , 100 mg Imitrex (pill form). I am very desperate right now to stop this!! My doctor is booking appointment a month ahead and I am almost at the point of no return...I know Imitrex should not be taken everyday , but I have no other choice I take about two a day and my Insurance doesn't cover some because of monthly expense or something like that.( only five per script. My Family does nopt understand what I go through and sometimes I ask myself WHY ME??? Please all suggestions are welcome I cant take this anymore I want a normal life!! :'( :-/ :-/[ :'(
