  • Lorazepam nearly killed me during cancer treatment
    Day 31 of cold turkey and I want to die. It is a roller coaster from body tics and sweats to rage and crying in one day. I felt so good the 4h day of c/t. It was like before my cancer diagnosis. My bowels are better off Lorazepam. I threw up during bowel movements from the pain. Off Lorazepam first normal bowel movement in over 2 years. Stomach so damaged by Lorazepam that I have absolutely no appetite. I force myself to eat. Neuropathy in hands nearly gone. Feet are better but slower. Lymphedema that appeared after one year on Lorazepam is now gone. I have full range of motion.
  • Androgel for secondary hypogonadism
    Severe swelling in legs, ankles and feet after being on my feet for more than one hour. Pain in calves and ankles. Feels like they're being squeezed or compressed. Pain dissipates after laying down for a few hours. Swelling never completely dissipates. Always some swelling in ankles.
  • Sleep apnea and vertigo
    Previous to Lorazepam, I was taking Mekclezine. Both makes me feel worst longer with vertigo. Usually when I fall asleep without my mouth guard, I get a serious bout of Vertigo for several days and the medications just cause more dizziness and the problem last even longer. I also find when I am under extreme stress, I acquire a bout vertigo as well. I am getting a better mouth guard made because the sleep apnea gets worse, the guard has gotten worn and my air way is getting blocked again, causes lack of oxygen and lack of oxygen causes dizziness. Which means to me one causes the other.
  • Valtrex 3 months systemic candida
    NOTE: IF YOU TAKE VALTREX FOR WHATEVER REASON, EITHER TAKE GOOD PROBIOTICS, OR GET ON A CANDIDA DIET. A MUST. You don't want to run the risk of messing up your colon with leaky gut syndrome after the yeast has done its damage. Please read the following story.

    My daughter has been autism spectrum her whole life but in December she really went crazy. She had PANDAS, (Pediatric autoimmune disorder associated with strep) Actually 3 bacterias and 17 viruses now associated with this syndrome. the antibodies to infant viruses and exposure to HSV1 (fever blisters) turned autoimmune and attacked the basal galia of her brain creating severe OCD, separation anxiety and irrational thoughts. The doctor put her on Valtrex 3 X day. He said it could produce yeast overgrowth take a probiotic. we did, one a day (not near enough) She had been cured! At 19 she came alive neighbors cried, her boss followed me to the car to say how great she was doing, talking, lively, social. etc. She started Valtrex 12/24/13. Life was good. I got her a smart phone (never thought she could use one) Then April of 2014 showed signs of hypoglycemia (yeast overgrowth)unknown at the time. Then May 1 had a nasty stomach bug. Went to family practice & ER. Its a bug going around. Well finally had the immunologist check for yeast, when she lost her memory and can't function without asking anything first. It's systemic Candida. The bloodtest showed the yeast was in her blood. You can also see it on her tongue. Causing memory loss, severe stomach upset, bloating, gas, burping. She cries every time she eats. We are on day 11 of Diflucan to kill the yeast. Oh yes, then the yeast dies and the toxins released by the critters produces symptons that are just as bad. Terrible fatigue, joint pain, low grade fever, flushed face. I went to the health food store and bought some homeopathic liquid that helps the symptoms.
    My daughter has been sick for ONE month.
    Will we return to Valtrex? yes. with caution. My daughter 'was here' from 12/24/13 to May 1 2014. Then I lost her to yeast. We will get her back.
    Just be sure and take probiotic, especially if you know you are prone to yeast infections. Once it is in your whole system, you would wish it was just an itch!
  • Horrible vivid nightmares
    was prescribed lorazepam for panic attacks. it finally dawned on me at 5:15 a.m.
