About a year ago I was prescribed Tylenol 3's for a concussion and I was curious of the high so I took 3 and was pretty well buzzed. I continued this usage with the rest of them as well as just using them for a good nights sleep. Then I found a couple bottles of oxycodone from someone who wasn't around anymore, I would take 3-4 and be very pleasantly high with my boyfriend all night long. Never had I been so happy. Eventually I ran out of those (heartbroken). I was prescribed Tylenol 3's again recently, it's been a couple months since I've had any good pills so I thought my tolerance would be low enough again to enjoy them. The other night I took 4 and was barely high but VERY itchy. Tonight I've taken 3 so far after having been drinking all day and I feel nothing. Why is this?? What can I do? Sorry this is so long!! I'm a first timer on here... thank you in advance to any responses!
