Well, a quick google search yielded results regarding plugging lyrica.. People said that it is an effective method, and that the rush hit a lot faster. And the high possibly lasts longer.
You want the pros and cons of lyrica? I have extensive experience with lyrica so I will give you a quick summary. Again this is information that you could have discovered in a quick google search but I digress.
Pros: _complete_ relief from opiate withdrawal, enhanced mood and even i would go as far as to say it gives you euphoria, you become a lot more social, any anxiety is gone, personally I find it to be very recreational, it potentates alcohol, benzos, and opiates. I tend to enjoy its effects. It is relatively safe in high doses once your body is used to it (I've taken upto 4500mg).
Cons: tolerance builds very quickly, if you take it for several days in a row and become dependent on it.. It has horrible withdrawals. The withdrawals are like an opiate and benzo withdrawal combined and possibly worse (but it's easy to avoid this if you taper down and dont cut it off cold turkey). It also impairs your mental ability after a few days of consecutive use (ie simple math calculations become difficult, your decision making ability is impaired, it's like a mental fog). It messes with your nerves, you will find your hands tremble. Sudden jolts mid-speech.
Overall, my opinion is that it is enjoyable once in a while. This will also keep your tolerance down.
