"i&#039;ve completed a starter pack and am 2wks into my second month @ 40mg/day. at week three of my starter pack up through yesterday, i felt better than i had in over a year! not unlike most users, i have also experienced gi issues that i hope will subside evenutally and i experience missing a dose for two days which made me panic a bit. yesterday, however, i began to notice new side effects - lingering ache at the base of my skull and my back aches and is stiff and i&#039;ve lost all the energy and sharpness that i previously experienced. based on many of the other user posts, i think i may need to go down on my dose. however, if i am able to return to the initial results for viibryd, it&#039;s definitely a win and would change my rating to 10!"
