"i have had an anxiety disorder and panic attacks for about 35 years. prior to the medication the best medications were the benzodiazapines but i have a high tolerance to them now. this has been very helpful- no pounding heart, no head ache, no feelings of dizziness and that i am going crazy. not sure yet if this medication is causing weight gain-too early for me to tell. i do have a little insomnia but overall i feel 100% better."
