I took Zoloft for quite some time and never felt tired. I think that it effects everyone differently. Only thing is that I always do speed before my workouts, the paxil should help after the workout is over by relaxing your nerves.
Same thing happened to me. I started taking Paxil and grew very lethargic and unmotivated as time went by. Still had bad anxiety so I started with Buspar along with the Paxil. I just went into hibernation at that point. Get off it while you can. It only gets worse.
i take Buspar for the anxiety. It works great for me. I tried Paxil but it made my tongue swell. I think everyone is different though. You might need to try a few different meds till you find whats right for you. Good luck.
