I was on Effexor years, didn't know it made the anixity symptom of feeling like heart failure way worse. Couldn't walk to the mailbox. When I came off it I only had regular headaches a few days. Sounds like other issues to me. I wonder how old you are when you mention sweats? My hot flashes started at 38. Severe nausea & upset stomach could be IBS & or acid. Don't eat spicy foods or letteuse?, anything that is hard to process. Go bland awhile. When I 1st got anexity so severely, I'd see the upset stomach min's after eating, didn't even know it was coming. Gross. Anxiety, depression & meds cause brain fog. This does not sound like it's from coming off Effexor. Hope you have insurance or a really good clinic you can go to. You need tests on you're stomach. I had a non emptying stomach. You get really bloated after a spoonful of food, couldn't eat another for like 8 hours. We have the same chemicals in our brains as in our stomach. Being on an antidepressant really helps the stomach. I finally got over the severe depresson so no longer take anything for that, then the stomach got worse. I was put on Reglan, but stopped taking it very quickly. They warn it can cause a drooping face, permanetly but I talked w/a lady that took it, she showed me her tonge? it's was so thick. She said she is embarrased to talk, people think she's retarded. I honestly didn't notice a thing about her speech. I stopped it when I saw that. It's the only med for it that works. For me, Lamitcal worked wonders & every med I'd been on I suffered the side effects bad. No side effects except it causes hair loss as does Clonazepam which worked pretty good to. If you get on it, or anything for mental health, make sure you take 10k of bioten & zinc everyday. I found out too late, too sick to notice I'd lost so much hair but bioten stopped the hair lose asap & put the bounce back in 2 weeks. I learned the hard way how severe acid can get. I'd get all over back pain that was unbearable for about 30 min's, then barf. Several times a month this happened, while I had no ins. Mom paid for me to see the dr. had pain below my ribs pretty bad, dr had no clue. He discussed me w/other drs to. Then it started on the other side but at the same time I had the aweful chest pain most know is acid, feels like a mac truck on you're chest. Then it hit me, the pain has been acid all along. It causes nausea, pain in the back, ribs everywhere but the limbs & head. Once my stomach was on fire. I tell everyone, cause when it hits you think you're dying and need the ER. Clonazepam for anixety worked pretty good for years but stopped. I shook so bad I had hardly no control. Makes you feel so very sick. Dr said, anixity attack, I said but it's 24/7. Oh they can do that. 12 years of this mess & no one ever told me this aweful illness that took me over was all anxity. Put me on valium 5mg 2x's a day. Controls it well but I'm still extreamly weak and have to move slow or the heart feels like it's died. I do pretty good but my thinking is so slow. At times I'vd had trouble counting money in front of a cashier, thats embarrasshing. I don't have attacks like most people, I live in a constant attack. I'm not afraid of a thing but my body thinks it is. We have the exact same chemicals in our brains as our stomach. So when you have mental health issues bad enough, you can count on the stomach eventually going wacko too. I hope this mess of a response has helped you in some way. What we read on line about anxiety always says an attack of fear & heart racing. Some aren't like that, it's an ongoing, never any breaks in it for me. I've never talked w/another person that has it like I do. I had great jobs for most my life & loved working. Want to work so so bad. I'll never be able to work again. I can hardly do a little housework here & there w/alot of resting & naps.View Thread
