Feeling tired and sleepy after work out :(

One of the reasons I work out is to have more energy kaso lang inaantok ako and super exhausted after :(

I lift as heavy as I can I spend 1- 1.5hrs in the gym I drink lots of water. I eat Carbs before going to the gym, then lunch na pagkauwi. Im on a calorie deficit

Any tips? hindi na kasi nagiging productive ang araw ko. I always feel tired and sleepy. 3x a week nalang ako nag gygym baka kasi over fatigue pero same parin :( help!
