Insomnia
"At first amitriptyline helped me sleep and for the first two nights I slept thoroughly. Now I&#039;m having the opposite effect and it gives me insomnia as most SSRI&#039;s do. Now if I take even 10 mg it is almost impossible to sleep that night and difficult to sleep for the next 3 days. It&#039;s been 3 or 4 days since I&#039;ve taken it and I still feel like it&#039;s interfering with my sleep. If you&#039;re sensitive to SSRI&#039;s do not take this for insomnia."
