I was put on Venlafaxine 37.5mg Am and PM: coping with care for my elderly Mother who argued everything! I have taken 28 tablets only once a day PM; because I am very sensitive to even OTC meds. I stopped the med. 8 days ago. I do not want to take drugs of any kind unless for BP, Cholesterol, type lowering, as needed. I live at 5200 ft went to sea level three days, returned home, and immediately felt VERY sick when exiting the car. Felt I could vomit never did. had tingling up my face, still do but a bit less. Took my BP 136/86, P 86. Next day was down to my normal 121/63. P 67. I can not find information stating these symptoms as withdrawal symptoms. My question is : is this withdrawal what I am experiencing. ? (My Dr out of the country, on call Dr I dont care for.) THANK YOU FOR YOUR EXPERTISE AND TIME
