Hi everyone,

I hope someone can help shed some light on a problem I've been having since August 2009.

Quick background: I've been on a mild dose on an antidepressant for the past 10 years. I started taking it back in 1999 for panic attacks.

Since August this year, I've experienced something new and scary. Something I can't 100% relate to panic attacks (yet), because I don't feel panicky when it happens! I know what a panic attack feels like.

I get a sinking feeling when standing around. When I walk I'm mostly fine. If I'm standing around waiting then it kicks in. I feel like I'm sinking. I begin to feel like the floor is a trampoline and I feel off balance. No dizziness thank heavens.

When I sit, I'm fine. This only happens in the afternoon and evenings. I seem to be fine in the mornings. Seems like whatever it is I can fight it off in the morning.

I've had all the tests done and everything seems normal.

Can anyone shed some light? Has anyone experience this? If so, did it go away? Is there a treatment?

Please help!

Reg.
