I have taken inderal for over a year now and it got me from attempting suicide the same day i started taking it. Obviously, it took about 20 days to start to work but i chose it as i suffer mainly from physical side effects from the anxiety. The mental side isnt so unbearable because i have suffered depression from the age of 11 and have always refused anti-depressants of any kind. Inderal especially worked for eventually relieving my heart palputations/rapid heart beat, extreme churning stomach and overall illness to cut a long story short. It isnt medically known to be addictive although i believe any form of medication is addictive if you convince yourself that you need it. It really has helped me and has continued to do so.
