Hey guys. Ive been on letro for 23 days now. .5mg then 1mg. then 1.5mg. then 2mg. and ive been on 2.5mg per day since. I am seeing improvement, but my question is, how long can I safely stay on it? I am starting to feel the sides, im very tired all of the time, am getting headaches, and have VERY low libido. Im deciding whether I should get another bottle or not because the one I have is almost gone. I am planning on tapering off the same way I tapered off and running nolva at 20mg for 1 week and then 10mg for another week. So should I get another bottle and see if it knocks it out completely and deal with the sides, or just taper off and start the nolva?
