Tollerance symptoms and conditions

Hello all, I Don't no where to really begin. I just started taking ambien cr for the first time last Wednesday. I was given the 12.5 mgs. I used to be on Restoril 30mg, but ive mustve built a high tolerance quickly because it stopped working. So i went on Ambien Cr. THe night before i took a restoril before my doctors appointment, then on the next day when i was prescribed ambien cr i took it that night, just one pill. It took a while for it to kick in, id say like a couple of hours, but i did manage to fall asleep. Next night I took one again, this time it was taking it a bit longer for it to work, so i chanced it and took a second pill. 30 mins later I finally started feeling the effects of the medicine kickin in which were drowsiness, blurred and double vision, and dizziness. So i thought to myself Maybe i need to take 2 of the 12.5mg every night. SO the next night i tried to experiment, i took 2 pills at one time, and in 30-40 mins time.. i felt the effects kicking in and went to sleep and woke up good., the next night did that again and fell asleep like a baby. but the next night. those two pills two much longer to kick in, id say it took about 5 hours. Im thinking and thinking why would this suddenly happen. I cant grow a high tolerance that quickly! Then it hit me that i was on Restoril for about 3 1/2 months and maybe my body is going through some withdrawal effects. Today I did feel really anxious. I took 2 ambien at 10:30pm Saturday night and im still up and its 5:20am Sunday. LOL. What do you guys think is happening to me? Could it be just that my body is detoxing itself of the restoril and im feeling some withdrawal effects?

Well...i'm only 17 years old and i have been trying EVERYTHING to get rid of my 2 week long heavy period and extremely severe cramping. I have been on 3 different kinds of oral BC and i would still bleed for 2 weeks. So i tried the Mirena IUD and that was the worst idea of my life. It went in fine but about 10 minutes later i was in a extreme amount of pain (and i have a very high pain tolerance, broke 3 ribs and didn't cry) i called my gyno back and he prescribed me a pain medication but it didn't work. After trying 3 different pain medications and an antibiotic i had enough. I went to the hospital and was prescribed percocet and that helped. I went back a few days later and had it taken out so now i am trying the NuvaRing. I put it in and a few hours later started cramping and having back pain. The next morning i had very bad nausea and cramping. Its about a week later now and i am experiencing headaches, nausea, quite bad cramping, bloating, tiredness all the time and i just don't feel myself anymore. I am calling my gyno back to see what he suggests but i'm looking for any ideas or suggestions until i get a hold of him. Thanks
