I have bladder spasms and I had a terrible time getting to sleep. The spasms are very uncomfortable when I’m lying there in bed trying to drift off. I read that some folks felt amitriptyline was helpful. I was first prescribed 25 mg. That put me to sleep!!! Very effective. I was pretty drowsy during the day though so I asked her to prescribe 10 mg. ( Until she did I cut the 25 mg in half) After a couple of months I tried to get off the amitriptyline just because I hate taking more meds than necessary. Yikes!!! After a few days I was back to the same problem but even during the day. Went back on the 10 mg and feeling relief. Sorry to be so wordy!!
