It is very unlikely to be prescribed an excess of Valiu in the case of alcohol detox. Rehab generally will only give the very minimum of medication, if any at all and for the shortest time. It can take days for Valium and related meds to clear the system, especially if unapproved doses have been taken.
Valium won’t sedate you completely, if that’s what your asking. it will make you feel calm and sleepy.
Yes, a great deal of stress can cause a heart attack, however, if your doctor has assured you that your heart is healthy, then my advice is to take his word. When you feel that your heart is skipping a beat, remember your conversations with your doctor. If you need immediate reassurance, visit the ER, most likely, they will give you something to calm you, and then send you home.
A psychotherapist would probably give you the strength to over come your anxiety attacks on your own.
Also, be sure to ask your health professional about any prescription drugs that can help you overcome your fears.
There is such a stigma because it has been heavily abused, and many people find it very addictive. Any drug that alters your state of consciousness/functioning that heavily must be dealt with great care since there is such a huge market out there for recreational/abusive drugs. Under the supervision of a medical professional, though, there is a much lesser chance of problems, though.
Valium is very good for anxiety and will relax you much the same as xanax. Yes it will help you sleep if you take one about half hour before going to bed.
Valium is a long acting Benzo and it will stay in your body for a couple days, but stop working after about 10 hours (it just depends on the person).
