Pregaballin withdrawals. Why is it so?

I am already on opiprol 100 mg .25 clonotril and 1 mg Loranza at bed time for anxiety and insomnia which arose in 2023 due to pregabalin withdrawal. However I had recovered completely and was on the verge of completely tapering my medicines. One day I took sysron n for my Pmos only for one day and the next day onwards I started facing regular tension type headaches again. I was compelled and put on pregabalin 50 for 10 days. My headaches stopped but I had to stop the medicine because of over sedation. Gradually after pregabalin discontinuation I started facing delayed sleep, hyperarousal & severe leg movement during night time. Currently I am only on n opiprol 50 mg .25 clonotril and 1 mg Loranza. But immediately after I take these medicines at night I become more energetic and more active instead of calming down and my leg movement becomes worse. Why is it so????? And I also feel like the medication is pushing away my sleep further more till morning. What should be done.
