"have been on effexor xr 75mg for about 1 year now for anxiety &amp; panic attacks. i had a constant odd pain in my stomach (like butterflys and hunger). i would sweat uncontrollably &amp; get dizzy &amp; faint if i was put in a situation i wasn&#039;t comfortable with. i went to a dr. who diagnosed me with anxiety and put me onto effexor. the first 3 days were hell, every bad review i read on google i could relate to, i even ended up going to the er one night as i felt so nauseous and felt like i was losing control and could not stop freaking out. the dr told me to stick to it, and promised it would get better. i&#039;m so glad i did. i feel that this medication has saved me. i can almost live a normal life again."
