Caffein symptoms and conditions

My experience with Lisinopril is similar to many others here. Mine is further complicated by the combination of drugs I am taking.
Due to my BPH I was taking Proscar and Doxazosin (4mg), the Doxazosin helping with hypertension as well (140/90). My doctor decided to add 5mg of Lisinopril to augment and help lower the blood pressure some more. He also liked the overall helpful aspects of the Lisinopril on the cardiological system. After about a week and a half on this regimine I was having dizzy spells and light headedness.....disconcerting when driving. I also had the infamous dry hacking cough noted my almost everyone. I stopped taking the Lisinopril and things went back to normal.
On my next visit to the doctor, he wanted me back on the Lisinopril but trying 2.5mg doses. That seemed to be OK for awhile. I have now added Flomax to my regimine and noticed the same dizziness problem. So I am staggering my pill taking which seems to be helping somewhat.
However, after three weeks on this program, I am having severe dry hacking cough episodes, 5-10 times per day. Also have to be careful when I stand up due to dizziness. Additionally, I am having sporadic insomnia problems that are out of the ordinary for me. Also, runny nose, sneezing and a tightening feeling in the chest and abdomen.....Almost like a mild flu. The tightening feeling is more like a caffeine overdose high...ergo the insomnia.
I attribute the hacking cough to the Lisinopril. The insomnia could be the same or possibly the Flomax. I'm not sure about the tightness. I plan to stop the Flomax next week when I go back to the Urologist and will stop the Lisopril at the same time and see what happens.
I would be interested in any input readers may have on my dilemma.

In August 2005, I nearly fainted from dehydration and went to the ER. I am a 47 YO Female and perimenopause may be a factor in my condition. At the ER, they found my BP was 230/130 and put me in the hospital overnight until I could have a stress test late the next day. Then I was put on 25 mg Toprol. My BP came way down, but within a week or two, I was lethargic, couldn't wake up, had no personality, couldn't accomplish the most mundane things. I also had frequent panic attacks that would send me back to the ER with BP in the 200 range. At the beginning of Nov., I went to 1/2 Toprol (12.5 mg) and felt much better (better than dead, that is) but still had surges in BP to 200 3 or 4 x a month; depression, and lethargy. At the end of Feb, my doc had enough, and this is day 3 w/o Toprol---I take Alprazolam 3X a day until we figure out what is next. Eating high-potassium foods, no alcohol, no caffein, has my BP in the 125-140/70-90 range the last few days. I FEEL LIKE A HUMAN BEING AGAIN! The headaches are awful, but I don't care, and they are getting better. Toprol is a bad drug because it stops adrenoline instead of regulating it. None of my friends on BP medication of other types have these problems! Get off Toprol!

Sounds like you need to be on Toprol for your fast heart rate. I had fast heart rate for about ten years. Around 130 bpm but then it started skyrocketing out of the blue at rest about 150 bpm plus palpitations, tightness and pain. Docs did tests and found nothing but put me on Toprol and Lisinopril. My heart rate and blood pressure is normal now. I also stay away from sugar and stimulants such as caffein. Hope this helps. I don't know of any side effects yet.
