Venlafaxine
"I started this medication a month ago for anxiety and depression.  Immediately I started feeling different during the first few days of taking this medication. But once i started taking the medication,  I started feeling better.  I still had episodes of anxiety, stress, and depression,  but they were more manageable.  The only negative side effects were yawning,  dry mouth and inability to remain asleep during the night. My GP decided to have me switch over to sertraline this past weekend due to the trouble of sleeping. I am currently on day 3 of sertraline,  and I don't feel quite like I was when taking venlafaxine. Need to give it more time. At least I know this one will work if need to switch back."
