about a month ago a friend had given me 2 watsons with a dosage of 7.5/500 hydrocodone/apap, and when i took it i felt absolutly amazing and was even nodding a bit. That was my first time with the drug. since then he hooked me up a couple other times with the same dosage i i still was feeling great except for last sunday when i noticed it didnt do much for me at all. Then this morning around 11 i took 3 of them, and then another 1 at 12. and as of right now at 1:05 i am not having a buzz at all and all i really feal is tiredness. My question is, is this my tollerance that is preventing me from getting high? its really wierd because iv only done it 5 times and the last was 8 days ago. i just can not figure it out.
