From an XA:00 short call I was called at XD:00 AM for a XJ:20 two day to ZZZ. I was awake from that call and didn't have solid sleep before. This was my first trip in X months and arrived 2 hours before to departure to get prepared and do the online form for State X. The next night I slept approximately 7 hours; but awoke several times during the night because I couldn't cool the room. I used a lot of caffeine to get through the flight home and arrived spent. 20 minutes after the trip the crew desk assigned a XF:59 flight time ZZZ1 ZZZ2 ZZZ1; 1 day on minimum rest. I was unable to get to sleep and called in fatigued. Undesirable pairing assignment along with operational fatigue.
Air carrier Captain reported undesirable pairing assignment along with operational fatigue.
