"dr put me on pristiq because i was having a bad time dealing with the loss of a loved one. it&#039;s my first medication and have been on it for 9 months, although it has relieved my mild anxiety i have decided that this or any other medication isnt for me.the weight gain has pprobably been the worst and only side effect for me, after 3 months i piled on 10kgs. on my pharmacists advice i have been lowering my dose on alternate days and am now on my third day without taking it. i feel like im a little tipsy/heavy headed by the end of the day and that&#039;s all so far but is bareable and i still manage to go about my day as normal, hopefully this doesn&#039;t last long. i have never experienced brain zaps either"
