12 week cycle; carry over of the Anavar?

[H2O]

I started my first 'course' early this new year: injectable Winstrol Depot (3 shots of 1ml a week) - Clen (which I might add, I really don't think gave me any results), and in to the 3rd week, trenbolone (yeah I know, you might gasp at this substance on a first cycle. I had no bad sides whatsoever though). Incidentally, the Tren was taken away from me, because I started to do it a bit more than I was advised. I actually think I've developed a fetish for injecting :-)

I intended to run the whole course for 8 weeks, but decided as I was only getting joint aches from the Winstrol as a side affect, which were bareable, to continue and do the cycle for 12 weeks.

At 7 weeks I acquired some anavar and after 2 weeks on it ... wow! It leaned me out considerably; I've never had so many comments on my physique, or looked so cut and I'm a beginner that has only been lifting for a year.

So ... (I'm coming to the question, truly!). I've stopped taking the Clen and am on my very last week of the Winstrol (week 12). I'm going on holiday in 4 weeks (21st April) and it's a beach gig!! Can I continue with the Anavar up until then?

This would mean that I would have run the Winstrol for a total 12 week cycle, starting the Anavar at week 8 of this cycle.

Therefore, by the end of the 12 week cycle I would have been on the Anavar for 4 weeks, with the wish to run it through for a further 4 weeks.

Incase the reason why I'd like to continue with the Anavar is not obvious: I'd love to maintain the leaness, even increase it some. I'm also starting to fret that by the time I get on to the plane I'll have lost some of the lean and hardness that the cycle has afforded me?

So whatca reckon?
