Ativan is in the class of drugs known as "benzo's" or benzodiazepines. They are depressants used to treat anxiety and panic attacks. Another of these is Xanax, a drug I have to take along with beta blockers to treat my thyroid illness.
When you were prescribed the ativan, the doc had reason to believe you had anxiety, but that can be caused by many other illnesses, including thyroid, parathyroid, and other glandular problems. In women, this anxiety can also be caused by incorrect hormonal balances, and/or estrogen problems.
Did you get a complete physical when you got your prescription? If not, I think one is due right away, with a full blood work panel - including a 5 test thyroid panel, and a urinalysis. You should not accept a life of continuous nausea and gagging. I think this has very much affected your appetite. When you believe you're going to get sick in a few hours, how the heck can anything to eat sound appealing?
Go first to your doc who prescribed your ativan. Print out the note you have written above, and don't leave until you get: 1. Some answers, 2. A treatment plan that begins immediately and 3. Some hope for a better future than you've been having.
Best in Health!
There are meds that can help with the stomach spasms. I take levsin but there are others. If you haven't seen a Gastroenterologist yet I would ask your doctor if this is an appropiate next step.
A good antidepressant cured this for me, gave me back my appetite and calm.
These benzo's send you up and down like a yo yo, they also have 'rebound effect' where you have the original symptoms only worse as they wear off.
