I was switched from Lunesta to Ambien bcs I'ms I had except it didn't work too well. This time it has seemed to work better BUT I think I am holding water possibly bcs I have gained abt 8 lbs n a few weeks. I feel like I am swelling around my lungs & the weight is making it hard to breathe. It could b any of the new meds so I'm wondering if anyone else has had swelling w/ it?

Thanks!
