Are you on a basal/bolus regime? If you're getting hypos then I'd suggest reducing either your basal or your bolus while the current conditions prevail. If you're not confident to do it on your own then phone your clinic. As a T1 I find my ratios and basal can change with activity and conditions....
Hypos are the bane of my T1 existence. I work very hard to avoid them and at the moment am mostly succeeding. Yes, many people feel like <insert favourite swear word here> after hypos, so you are not alone.
I wonder if the sweating is also a symptom of the hypo. Ideally you'd catch them before you get too low, because (in my experience anyway) the lower you go the worse you feel. Do you have access to a libre so you could head them off before they happen? How low are you going?
But don't hesitate to call your clinic for advice. They are there to help you.
Good luck.
