I was taking 20 mg of paxil and nothing happened so i started taking 30 and for what seemed like months i was very tired all the time and sleeping for very long periods and then one day i felt much better.my anxiety and depression were at a tollerable level and i had alot more energy.i am wondering if taking 40 mg will make me feel even better than i do taking 30 and also concerned if the switch will make me tired again all the time.i feel like i am almost there but just not quite.it has been about two weeks since i first noticed a positive change.and feedback would be greatly appreciated.thanks and god bless
