"started amitrip. for fibromyalgia  5 weeks ago @10mg. i started it on a friday night after reading the reviews in case it made me groggy.  the first two night/mornings i slept significantly throughout the day.  but by monday morning i was fine, and up by my usual 5:30am school route to take my children to school.  i felt a slight difference.    no other side effects. my pain was still there but just slightly less.  doctor moved me to 20mgs after 3 weeks.  again, groggyness but only the first day.  but wow!,  i noticed my pain is about 75% gone after the 3rd day or so. i still get pain if i over work myself.  but i just need to moderate my self.  looking forward, hoping the next increase will be my miracle.  very happy!"
