"klonopin is the only anti anxiety medicine that works for me. i have tried ativan and xanax- they both do not take away the effects anxiety has on my body (tense muscles) and when they wear off, i feel way more anxious then when i take them. i have been on it for 13 years and yes i have developed a tolerance and need to take 3 x 0.5 mg per day, but for me it is the only anti-anxiety medication i will ever take."
