Due to permanent tension in my body and insomnia, a week ago I started taking 150 before bed. The effect was immediate - the tension disappeared, my head works normally, I sleep well. Unfortunately, I also immediately lost the ability to have an erection, and even if I manage to induce it, I am unable to ejaculate. Is this normal and will the erection come back over time? When? Is there a drug that has a similar effect but does not cause erection problems?
