Desvenlafaxine
"I just recently started taking it (a little less than 2 weeks ago). The first day I was very giddy and kept getting a tingly feeling from my head to my toes.  Than it stopped after the second day but I did experience the hot sweats, loss of appetite, nausea and lack of sleep. The sleep was the worst thing! I woke up almost every hour every night for 2 weeks straight!  I was either waking up and feeling wired or waking up because of the hot sweats and I'm only 23!  If you want advice, do not take caffeine until some of these side effects go away because it will make you way more wired than usual and you'll feel very uncomfortable.  Also, do not DRINK ALCOHOL. 1 sip of wine and felt dizzy for at least an hour!"
