How long of a T-break should I take?

I'm wanting to switch from carts as my main way of smoking to flower. I've smoked nothing but carts for the past year. I want to switch to flower, but I saw that I would need a LONG Tbreak for flower to work on me again. I smoked some flower this week and it was hit or miss. So, I was planning on going on a month break. Is that long enough? I know that everyone is different and reacts differently when it comes to breaks, but I'd like some input. Any opinions would be great! Thank you in advance 🙂

Edit: Thank you, guys, for your input. It all helped so much. I went and grabbed some CBD gummies and took 2. I feel kinda good? Not really a high, but a state of peaceful unawareness?

While getting gummies, the cashier told me to drink as much orange juice as I could in two days, then a gallon of water a day for two days. Then, wait two days to smoke. She said it would completely reset my tolerance. I call bullshit, but if it works for her, it works for her lol
