"i have been on pristiq for 2 months now.  i have past digestive problems, so when i was diagnosed with major depressive and panic attacks, i was very hesitant to try any medications, especially with nausea and constipation side effects.  within two days, i felt tired but things began to seem not so overwhelming.  within a week, i was able to cautiously get back into work and life, and now, i have had only one panic attack, and have had nothing other than a headache if i don&#039;t take it on time.  my energy levels returned within one week, and sex drive within two weeks.  i have even lost 10 lbs.  i never realized how bad depression was until i began to see colors again, smiling, and everyone kept asking me if i had grown and lost weight."
