As you were, I was a bit worried about taking the subs so close to the MS (esp. since it was time release!) so I just started with about 1/2mg Sub. I didn't have any issues after about 30-40 minutes so took another 1.5mg. No problems.
Before my subs induction I had 500MG's of codeine about six hrs before the doc shoved 8MG subs under my tongue. No issues then, either.. of course that's a much shorter acting opiate, but again I had no problems.
I read SixPartSevens method of using alcohol to increase absorption sublingually, but I haven't tried it yet. It makes sense, just doesn't sound pleasant to do @ 6:00AM. I'm also trying to get my hands on a bottle of Everclear. (Just a quick jump across the border for that though.) I HATE having that tab under my tongue regardless so that's probably another reason I probably haven't tried it yet. (Not to mention the psychological satisfaction of sniffing the subs - I used to really like coke.) Thanks for the info though - I know there are tons of people that will read this post and look it up.
Most people just jump to the last page and start from there anyways. hahah
Have Fun!!!
