"the first few days i also (like others have posted) yawned non-stop. i was also sick to my stomach for about a week. the second week in i noticed that i lost the ability to get turned-on as easily by my fianc&eacute; which was incredibly annoying for me. she used to be able to have a couple orgasms during sex, and we made love several times a week. i&#039;m really frustrated because i&#039;ve lost such amazing sensation sexually. i&#039;m going to ask my doctor to taper me off of it, as soon as i can."
