I did have 6 alcoholic drinks (single measure) because I do have a heart arrhythmia so I don't over do it. This attack lasted around one hour. The vomit isn't alcohol or food it's bial I do also have palpitations. The doctors clinic isn't open today so is there anything you could suggest to ease it until tomorrow? Also is it usual to be in pain and feel unwell for 12 hours after the attack happened?
