"i switched from effexor when pristiq became available at the suggestion of my psychiatrist. effexor was an improvement on my previous medication but i still suffered some anxiety and i experienced increased sweating. pristiq seems to have reduced my anxiety levels and the sweating may have eased slightly and also, my mood improved. more recently i have also been prescribed dextroamphetamine (for adhd), which improved my mood further, enabling me to halve my daily dose of pristiq to 100 mg. i did this with the aim of reducing my sweating coming into summer (i am a resident of sydney, australia where the summers are typically hot and humid)."
