Think of it this way, what if you are being hypersensitive and what if it really is the onset of gyno?
Too sensitive: Well, if you don't take the nolva, you just saved all that nolva. If you do take the nolva, you just wasted $20 worth of nolva.
Gyno Time: Well, if you don't take the nolva, you can walk around with breast tissue, or you can get a surgeon to remove the tissue for only $3000. If you do take the nolva, and it is enough (nothing works 100%) then you saved yourself hearing 'nice rack' from your friends and/or a cosmetic surgery costing several thousand dollars.
Which would you choose? Me, I'd be looking for some arimidex because I would be taking so much nolvadex you would think I was a female breast cancer patient (which is why it's prescribed anyways).
