Amitriptyline withdrawal very hot lower body (very hot legs) not restless leg syndrome

Hi guys I have taken 70 mg amitriptyline for 17 years for insomnia it's been now 6 weeks I had my last tablet as I decided to come off cold turkey. In these past 6 weeks I had slept a total of 7 to 8 hours (in 6 weeks).
I have researched before coming off these horrible meds that the withdrawal symptoms are horrific and I am going through all. Is there anybody who came off amitriptyline successfully any tips help
Any herbal remedy for SLEEP I have tries 5-htp but it gave me sire throat.my Main problem at present is very hot lower body(especially legs becomes very very hot when I ly down on the bed) it's not restless legs syndrome as I don't feel pain in my legs but my lower body becomes very very hot and I cannot sleep because of this. I am sure it's amitriptyline withdrawal symptoms as I never had any problem before.
Anybody who had this problem when withdrawing from amitriptyline please help any herbal remedy for this.
Thanks and how long these withdrawal symptoms last. So many people say it will last 6 to 8 months for body aches,nausea,head aches,abdominal cramps......anyone who went through amitriptyline withdrawal please message me thank you in advance.

add melantoin to the valerian root . its my go too combo. 6 mgs melantonian and at least 900 mg of valerian root. there is a good otc product called alteril that works well for me and many others I know also.
