Neo-Synephrine and heartbeat

This may answer alot of questions. I've been using neosynephrine for 40 years. One to two bottles a week. Started with 1/2%, I think that's what it was, and graduated in no time to 1%. I've never been able to get off for more than a couple of days. I have had a skipping heartbeat for 33 years, which may or may not be due to the neo. Sometimes is skips pretty steady, and other's just occasionally. I had a stress test last week that came back positive, and went for a heart cath. It showed no blockage whatsoever, so it was a false positive. Due to all this, I decided to stop last Wed., so I diluted my nosedrops in half with Saline Nasal solution. Since about the 3rd day, Sat., I have had all kinds of symptoms, including low blood pressure, fuzzy in the head, and not able to think straight. Today it is mainly the fuzzy in the head. Almost like you're somewhere else looking in. I will continue to try and get clear off, if anyone knows anythink else about getting off, would appreciate knowing the symptoms.
