I was sluggish and tired all of the time. I had no sex drive at all and could not sleep at night. After one dose of the implantable pellets, I started feeling less tired and sluggish after about three weeks. I also have been able to sleep so much better and I'm way less irritable, which my husband is very happy about. I've also gotten my sex drive back and no more night sweats! This is one of the best treatments that I have ever done for myself.
