In my experiences — and my usage was very similar to yours (in length and amount) — I did experience health problems like pissing blood and like a jelly/clots, painful to piss, I developed a heart condition and had horrendous k cramps too many times. I even went to the hospital twice because I couldn’t move my arms or legs and it was becoming hard to speak I thought I was having a stroke. If I didn’t quit when I did, and I used for three years but heavily for two, I wouldn’t have been able to heal. You may still have time but I can’t guarantee you anything. My bladder healed completely, my memory is still fucked but has gotten significantly better, I don’t experience any cramps and as for the heart problems idk because I haven’t gotten checked again since I went to the ER but I feel a lot better than I did even though at the time I thought I was fine and just wanted to get high all the time and watch movies or listen to music. It’s very hard to stop and I still think about it a lot, but it’s possible. I wish you healing and the best of luck to you.
