I have been taking tadalista 40 mg a day which is a form of cialis. I started getting bad heaches and severe leg pain. the headaches are starting to go away but the leg pain is pretty severe. I cant even sleep at night. Will this go away??? I have been off the cialis for about a day and a half now and I wonder how much longer tell its threw my system. I wanna be able to sleep again. anyone got any idea how much longer i will have to deal with this?
