Savella
ibromyalgia
"Have been on this drug for the full four weeks now.  I've noticed in an improvement in my energy and mood.  The muscle pains have all but gone too.  I did have sweating/hot flashes with it but those are better now.  Luckily my insurance covers it but it's still $60/month.

I also noticed the increased heart rate so I quit drinking caffeine during the day and keep my beer/wine consumption down a lot.  Increase your intake of water as that helps with the head pounding feeling.  I also take Ambien so my sleep has not suffered.  Consider taking something to help you sleep, at least until you get used to the medication."
