Glad the side affects of the discontinued are leaving your system. When I have been taken off some of my meds (anti-depressants) I had a period of withdrawls from the med leaving my system kind of like a detox thing, anxiety, shakieness, and insomnia.
Is your lack of sleep due to not being tired or repetative "worries" running through your mind as you try to rest? I have had times when I am just so overwhelmed with the situation worries of my life that would just over and over in my thoughts that it caused me not to get any sleep. Tylenol pm is a good otc sleep aid, and for a lower price and the same active ingred. Is Benadryl or the generic antihistimine in Benadryl. The Pharmacist told me that when I inquired about otc sleep aid prducts, he told me that they all basically were just beadryl with a bigger price tag. I can get the generic form of benadryl for less than two bucks.
I know the misery of feeling horrible and being tired an in physical pain and not being able to sleep, I would see about calling dr office, if this continues. They may be able to prescribe a sleep aid or something to help you rest.
I hope you are able to get some sleep,
Take care
