"Pristiq has been a catch 22 for me. The medication has helped to stablize my mood and some thought process, but there have been multiple draw backs. During my first 2-3 weeks of taking the medication I was even more tired, had to sleep for at least 3-4 hours after taking the medication, which prompted taking it at night. The BIGGEST DRAW BACK for myself is that Pristiq has made running and physical recovery double in time. I've added almost 1 minute 20 seconds off of my run time additionally it has become extremely difficult to find the motivation for working out. Because I enjoy competing in triathlons this side effect for me has been devastating. For instance, an 8 mile run that would take me 44 mins took me 1 hour and 9 mins this morning."
