Theoretically, Cialis should help cold feet because it is a vasodilator and improves blood flow.
You could try supplementing vitamin C 250-500mg/day (makes me feel less cold) and CoQ10 200mg/day (general anti-inflammatory in case your immune system is attacking your nerves). Monitor for side effects - vit C might make you overheat, CoQ10 might exacerbate the delayed orgasm (anti-oxidants in general do that for me).
Some infections and cancers present as night sweats so be vigilant about these possibilities. It is not all about hormones.
