I just started taking this drug three days ago, and I am already ...

i'm sure your husband is right- your body is trying to get rid of the drug. i'm very curious as to two things- one, that your doctor wants you to go to the office to get your blood pressure taken, something she can bill to your insurance. buy a little home BP machine and you can monitor it yourself everyday without a doctor's visit.
two, you say "I am so scared that she won't lower the dose"- what's up with that? if you don't want to take it, don't take it or you can cut the pills in half. she can't force you- it's not like she's going home with you and tying you down. take back some power and control over your health!
now, a word on one aspect of this drug- its a potassium sparing drug which means that you need to eat a low potassium diet while you are on it; otherwise your potassium levels can get too high and it can damamge your heart. the irony here is that potassium helps regulate blood pressure and all whole fresh foods contain lots of it. so lisinopril, a drug that is meant to help lower your blood pressure, forces you to not eat the very foods that would help keep your BP regular naturally!
what's your diet like? if you eat lots of fresh vegetables, fruits and whole grains, you'll be getting plenty of potassium and very little sodium and your BP will probably settle itself.
but as long as you are on lisinopril, you're going to have to eat canned, soaked, chopped and cooked to death vegetables, a bagel will be preferable to a rich whole grain bread, coffee over fresh pressed fruit juice.
it's ridiculous, really

Well, I don't have insurance, unfortunately, and I go to a doctor who does not accept insurance. She runs a clinic for people without it, and takes blood pressure readings for free. So, she's not trying to make any money off of me. However, I think she is very old-fashioned in her opinions, and won't listen to me about the side effects.

I went back to her two days ago, and my bp was high again. Again, I know part of this is nerves because I was extremely nervous (I always am at the doctor), and I am overweight. I feel that if I can lose the weight, my bp will get to a good level. I am going to buy a home bp monitor this weekend so that I can start tracking it myself. I told her about my fainting, and she told me that I must have been sick and that it wasn't the lisinopril! I was really irritated about that. I mean, I've been sick plenty of times in my life, and I've never experienced anything like what happened last Sunday. I know it was the medication. There's a huge sticker on the box that says not to drive until you know what your side effects will be. She told me to keep at the same dose and that I will get used to it. I have not taken it since last Sunday.

I have a plan right now. Since I found out about this and the diabetes about a week and a half ago, I have started walking every day and have changed my diet. We are going to see an acupuncturist next week as well. I am going to give myself some time to try and bring my bp down on my own, and if it doesn't work within a month, I will try meds again. I am trying to get serious about my health and fix my body, not just take meds and keep living the same way I have been. I just cannot tolerate this drug.

There are many natural products for high blood pressure and high blood sugar issues . . . instead of taking drugs that cause side effects. Unfortunately, most drs. all they know is to push drugs.

garlic is great at lowering BP. it's fantastic that you are walking and changing your diet. accupuncture is terrific.

the best thing is that you seem to have a strong will and are not blindly following doctor's orders if they don't make sense to you

Definitely make sure you don't need your Gallbladder out. I take Metformin for my PCOS and I was having the worst symptoms, I thought for sure it was all from the Met. Nausea, throwing up, diarrhea etc.. If you find greasy food is the worst thats a big sign it's a Gallbladder problem. Then I had a horrible attack and went to the ER. I had to have my Gallbladder out after recovering I still have issues with diarrhea but it's nothing compared to before. At least now I can cope, some days are bad and others I'm just fine. Good luck!
