Violent thunderstorms; minimum rest; an unnecessary call from scheduling; and possibly an impending ...

Narrative:

Got into destination with minimum rest available; thunderstorms came in right after arrival. Massive amounts of lightning and loud thunder most of the night. I had trouble falling asleep initially; I noticed the clock still just before midnight local with only a few hours left to sleep. It seemed I woke up about every 30 minutes and/or whenever the thunder woke me up. Then around about two hours before scheduled wakeup time; crew scheduling woke me up notifying me of an 'adjustment' to my schedule. Thanks for that. It could have waited. So overall; I may have gotten somewhere close to 4-4.5 good hours of sleep; only to be woken up early; then had to deal with more thunderstorms; and deviations on the way. Honestly; the back of my eyeballs hurt; my head hurts; my whole body hurts. And that feeling you get; prior to getting sick; that's how I feel. Just plain communication (on my part) was sketchy. I almost felt as if I was in a haze. Although; the thunderstorms woke me up with a bit of adrenaline while we were trying to fly through and around them. I asked several times for the first officer to repeat things he said simply because I heard him; but I didn't hear him; if that makes sense. I felt as if it took me twice as long as normal to get a clear thought through my head. I felt unsafe and a potential risk to my job and my crew.
