period pain
"I found it to be very effective in the first 6 months of use. My period pain would start to subside within the first 15 minutes after taking it and it lasted for about 12 hours. Now it takes at least 1.50 hours for the pain to even start to subside and it only lasts for about 6 hours. It makes me so tired to the point where I have to take a nap and when I get up from my nap I feel extremely tired and "out of sorts". This feeling usually lasts the rest of the day no matter if I take a nap at 11:00 AM or 4:00 PM. So I only take Ponstel now when it is absolutely necessary."
