Rifat, if it makes you feel any better, I always deal with a little bit of insomnia when on cycle...it doesn't matter what I'm taking. Now if I'm dieting, it's not as bad because I'm so freakin tired, but it's still something I have to deal with. Like everyones said, be careful with the sleep meds...you do not want to get addicted to these. I got severely hooked on these a while back and that is a mess...it took forever to get back to normal. Now days, if I have trouble sleeping I'll take a little Sominex, but I try to keep this as minimal as I can. One more thing, watch your caffeine intake, especially later in the day...this can effect you a lot.
