If i get intermittent erections after taking viagra (sildenafil) during the night is that a problem?

No: Nocturnal erections are normal and it normally occurs with rem sleep in healthy males. Nocturnal tumescence testing actually involves measuring nighttime erections on male patients to rule out vascular source for erectile dysfunction
